Hydrochloric Acid In The Stomach Dissolving Research Paper

The process of extraction removes a desired compound from a mixture. Because molecules with similar intermolecular forces are more soluble in one another, organic compounds are usually dissolved in organic solvents. Based on the solubility differences of the organic solution and water, when mixed, two distinct layers form. Sometimes, small amounts of the solvent may dissolve in water. To prevent contamination of the product, a drying agent is added to absorb the water molecule. The organic solvent is evaporated from the organic compound through the use of a rotary evaporator. It is a quick process that reduces the pressure and thus the boiling point of a liquid. In this experiment, eugenol was separated from mixtures containing methylene chloride and hexane. If was predicted that methylene chloride would be the most effective solvents due to its immiscibility to water and low boiling point.

The purpose of this experiment is to determine an unknown concentration of acid (hydrochloric acid) with a standard solution of a base (sodium carbonate) using titration method.

2. Describe any evidence that a chemical reaction occurred when you added 6 M HCl to the solution of sodium acetylsalicylate (the conjugate base of aspirin) and explain why they took

10. Which had the greatest average 1- OD (amount of bile acid adsorbed to meal particles), the standard meal with bile acid or the

The goal of this was to successfully accomplish the synthesis of para-Chlorophenoxyacetic acid. In this experiment, para-Chlorophenoxyacetic acid was synthesized from 4-chlorophenolate and chloroacetic acid using an SN2 reaction. The product obtained was determined to be the para isomer of Chlorophenoxyacetic acid. This was confirmed by the melting point of 157.3-157.9 ◦C. The percent yield determined at the end of the experiment was 37.83 %. The TLC analysis showed that P-Chlorophenol was less polar than P-Chlorophenoxyacetic Acid because it had an Rf value of 0.38 in comparison to the value of 0.33 on a 50:50 hexane and ethyl acetate solvent mixture. In the NMR comparison, it was shown that both the starting material of chloroacetic acid and product contained a peak of integration two around 4 ppm representing the acidic proton. In the FT-IR comparison, it was determined that the Chloroacetic acid and the para-Chlorophenoxyacetic acid both had an OH bond at 3416 cm-1 and 3429.72 cm-1 respectively. The Chloroacetic acid and para-Chlorophenoxyacetic acid also both had a carbon-oxygen double bond at 1648 cm-1 and 1654.81 cm-1 respectively. The para-Chlorophenoxyacetic acid also contained a peak at 1236.18 cm-1 which represents the C-O-C bond.

Digestion is a complicated process that uses many different processes to digest food efficiently. It is necessary for not only us but for almost every organism. A major part in digestion is pH or how acidic or basic a substance is. pH helps digestion happen, the question is for the Stentor and the Rotifers at what pH ranges does their digestion occur? We will test that by using pH indicators, and observing the digestion happen under the microscope.

Acids and bases are very important. We clean with them, we eat them, and we use them to help in chemistry. The ions who are the cause of acidic properties is H+ ions, or protons, and for basic properties, it's the OH- ions, or hydroxide ions. all of that is based on a theory called the 'dissociation of water' (which is H2O--> H+ + OH-). So the more H+ there is in a solution, the more acidic the solution is, and the less H+ there is, the more basic it is. That is why there is H+ in solution factors on the pH scale. The more protons present at one time means the pH scale decreases, and the H+ present goes down. The pH scales job is to measure the acid and base levels of a substance and how strong they are. The numbers on the scale go from 1 to 14, with 1 containing the most hydrogen ions and 14 having the least.

While a healthy digestive tract’s buffering systems should prevent cola’s acidity from directly reaching your bloodstream, these countermeasures can be costly.

Hydromorphone, also known as Dilaudid, is an opioid agonist analgesic. This drug produces “analgesia, euphoria, and sedation” (Karch, 2015, p. 608). It is used to treat moderate to severe pain in patients who have uncontrolled, chronic, and post-operative pain. Hydromorphone is notorious for causing adverse drug events (ADE).

Chlorine has 17 protons, 18 neutrons, and 17 electrons. It's atomic number is 17 and the atomic mass is 35.45. Its symbol on the periodic table is Cl.

Society during 1800’s was vigorous due to the comparison of risk to use chloroform, with women being Snow’s main target in research there was still confusion amongst pubic. Despite this religion had mixed views about chloroform, some would refuse its use and others had no reasons for their opinion but some had no concerns due to the Queens uses. A few religions views were supported by media, whereas others supported Simpson’s views and medical support was similar in the way of split views of chloroform, but was widely discussed but some medical leaders believed chloroform was unethical. The Church of England preached the uses of chloroform, but because of the Queen’s uses their views changed because of the success. In the 20th century, chloroform

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.

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

Another kind of incident that occurred before when Ken should've done something when he had the chance was when David sniffed chloroform. This substance, chloroform, was known as a very dangerous substance to have around your house. A chloroform is a, “primitive anesthetic commonly used during surgery in the mid-18002”(silverstein 17). Chloroform was initially used to make people sleep so they wouldn’t feel the pain of surgeries. It could be dangerous if you sniff it a lot. But David didn't care about that. Reading his favorite book, the golden book, it, “urged readers to sniff carefully…David took the challenge, but apparently sniffed too vigorously and ended up flat on his back. He estimated he was out for more than an hour”(Silverstein 17).

This experiment was conducted to find the rate law for the reaction of iodine with acetone. This was found by using the method rates. The orders of acetone and hydrochloric acid is one while the order of iodine is zero. The procedure was meant to notice the disappearance of one reactant, Iodine.
