Stomach Acid Lab Report

We measured 3 mL. of catalase into eight test tubes because to us, it was the right amount to place into a test tube, without having any overspills. For two test tubes, we added 9 mL. of vinegar and 9 mL. of Hydrochloric Acid (HCL) to another pair of test tubes because this amount was reasonable for not being too much that it overpowers the catalase and not too little that we may not see any impact. Now, we repeat the same process of adding hydrogen peroxide (H2O2) and sodium hydroxide (base solution) to the rest of the pairs of test tubes with catalase. Our group then analyzed each pair's appearance and its amount of foam. Thus, we can compare it to later results from the second experiment that would be conducted as the following. Afterwards, our group individually takes one tube from each pair, containing the same base or acid, and put it into a beaker filled halfway with ice for two to three minutes. We believed this amount of time was the most efficient for us to be able to finish the lab and collection of data. At the same

For our hypothesis we thought that the seltzer would dissolve the alka seltzer the fastest, because the seltzer was already carbonated. After doing the experiment we found out that the seltzer was the 2nd fastest at dissolving the tablet, and the water dissolved the alka seltzer 6 seconds faster than the seltzer. This being said our hypothesis turned out to be wrong because the water (fastest to dissolve the alka seltzer) has fewer chemicals, so it dissolved the tablet faster. We thought the less chemicals the slower the alka seltzer would dissolve. Although after conducting the experiment we found through data that the more chemicals in the liquid, the slower the tablet would dissolve in them.

Germination is affected by many factors including pH. The pH scale is a logarithmic scale that runs from 1 to 14. If the substance ranges from 1-6 it is considered to be on the acidic side, however, if the substance ranges from 8-14 it is considered to be on the basic side. A pH of 7 is neutral, which is typically the pH of pure water. Plants typically have a specific tolerance for pH ranges in which they can flourish.

To start off the experiment 25mL of water was placed into a labeled beaker and tested for the pH using pH test strips. Next the antacid tablet was placed in the solution and timed for how long it took to dissolve the tablet. Finally the temperature was measured. This same process was repeated for the acidic solution, and finally for the basic solution. After each experiment the pH, the reaction time, and the temperature of the beaker were recorded into a table. For this experiment the independent variable was the substance used (acid, neutral or base), and the dependent variable was the reaction time of each substance. The constant conditions of this experiment included the amount of substance being used, and the placing of one antacid tablet into each beaker. The experimental group was the acidic and basic solution, and the control group was the neutral

Absorption – “How the drugs enter the circulation process through the body, and how they resist general breakdown by the stomach, liver, and the intestines”. Some of the factors that affect the absorption of drugs in the body is as follows, “acidity of the stomach, Physiochemical properties, Presence of food in the stomach or intestine, and Routes of administration”,

pointer and will be dreary in an acidic arrangement and will hand pink over a fundamental arrangement. pH is the measure of the acidity or basicity of a fluid arrangement. On the off chance that we perform our tests effectively we expect the NaOH-HCl answer for turn blue, the Ascorbic Acid-NaOH answer for turn a shady blue since fillers in the tablet won't be totally solvent in water, and the Baking Soda-HCl answer for turn clear. A solution is a fluid blend of a solute consistently dispersed in a dissolvable. A fluid arrangement is a solute consistently disseminated in water. A solute is a substance that breaks down in a dissolvable. A dissolvable is a fluid that can break up a particular measure of solute. A large portion of our estimations will be in molarity (M) which is signified by the  number of moles of the solute isolated by what number of Liters of the solution. When blending chemicals with water dependably include water the chemicals not the other path around as this could be perilous. We will institutionalize NaOH since it ingests water and CO2 from the air and KHP serves to precisely measure the fixation. Institutionalize intends to convey an answer for a known

What if the density of the pill affects the dissolving time in the hydrochloric acid? During this experiment, this question will be answered. The denser the pill, then the longer dissolving rate when time is a function of the dissolving rate. Tablets, coated tablets, gel capsules, and hard capsules will be tested, and all of these each have a different densities.

This activity was performed over two days. In this lab I learned how to read labels better on food products. I also learned how challenging it is to keep track of everything you eat. After putting in the data on Monday I realized that my total of calories consumed were lower than they are supposed to be. My BMI number is 20.4. Having that as my BMI is why I need about 2,068 calories a day. On Monday I consumed 756 less calories then I should have. A few things I noticed about my data are; overeating carbs, under eating fiber, and under eating protein. My level of carbs 65 grams above what it should be. Both fiber and protein were under with fiber being 17 grams lower and protein being 6 grams lower. Now taking a look at my

Inflamed tissues from Ulcerative Colitis (UC) patients show increased oxidative and nitrosative damage, leading to accumulation of mutations and dysplastic progression27,28. Infiltrating leukocytes from these patients have increased ROS production in basal conditions and in response to different ligands29. Since TLR4 mediates ROS production in leukocytes22, it is easy to speculate that immune cells drive pro-tumorigenic effects of TLR4. However, bone marrow-transfer experiments in our lab demonstrate that non-immune TLR4 participates in development of neoplasia8. Furthermore, we have shown that epithelial TLR4 activation predisposes to colitis and CAC6. To understand the role of epithelial TLR4 in neoplasia, our research has focused on the

The classes fastest information processing time occurred during the color sort with preview trial. Following, was the suit sort with preview trial. Next, the cards that were sorted by color without any preview followed. The information processing time that took the longest occurred when the cards had to be sorted by suit without preview. These results did not support the stated hypothesis. While it was expected that the suit sort trials would lead to the longest information processing time with or without preview, the results showed that any trial with preview had the fastest information processing time.

Science Script Introduction; Everyday, we eat and drink, often taking it for granted. Most people disregard what happens within our body during digestion process, So, what really happens in our body when we digest? Scene 1; Mouth Digestion first begins in the mouth, using mechanical digestion. Incisors first bite into the food breaking the polymers into smaller monomers. As the food goes further into your mouth the food is then ground by your molars.

In this lab new equipment was used such as the electronic balance, the pipet, and the graduated cylinder. Some of the different techniques that were used in this lab were the water displacement technique and the filling of the pipet. The two different tables that were used in this lab were the Qualitative data table and the Quantitative data table. In the Qualitative table there were only observations and no numbers. In the Quantitative table numbers were used. In this lab there were some formulas that were required. The formulas included density, water displacement, specific gravity, and percent error. In this lab percent error was also used. Percent error is used to determine the accuracy of the calculations acquired in the

One day me and my friends were going to science class, we were so excited to go because we were doing an experiment on the digestive system the whole class went except tommy, when told him to stay to keep the class safe. When we left he opened a bag of chips and we sat in his hand and he ate us. First we went inside the mouth were tommy cut and grinds and triggered his chemical in saliva glands to work with the mechanism of the tongue salivary glands in your mouth makes salivary amylase, which begins the digestive process by breaking down starch when you chew your food,that's how the food into was cut into smaller pieces, after that he swallowed the food and we went down the esophagus we saw epiglottis which is a flexible flap at the end of the larynx connecting it to the throat, it acts like a switch permitting air to pass through as you swallow the food, then we saw the peristalsis , a peristalsis is a muscle contracting in a wave like motion to move the food to the stomach after that we saw the lining of the esophagus, the lining of that esophagus is called a mucosa it runs down the windpipe and heart in front of the spinal cord to prevent food from just dropping into the windpipe, this is starting the digestion process, after that it takes us down the stomach, then

I’m doing my report on Reglan. Reglan is a medication they give to people with digestion and indigestion problems such as Gastroparesis. What’s Gastroparesis? Gastroparesis is a partial paralysis of the stomach which results in delayed emptying. The reasoning of why I chose Reglan is, because they prescribe it to people that have Gastroparesis, and my niece was diagnosed with it at age of 12 weeks old.

The statement, the stronger acid has a higher pH than the weak acid , is proven to be false. pH is a measurement of the concentrations of hydrogen and hydroxide ions. To defined the pH we used the formula -log10[H+]. With this example H+= 1.0e^-2 equal the pH of 2 and H+=1.0e^-4 equal the pH of 4, we can see that the lower the pH values the concentration of hydrogen ions is higher when the pH goes up compare to when H+ decrease. HCl is a strong acid in which it completely ionize in water and become H+.
