How Temperature Affects The Rate Of A Chemical Reaction Lab

In reference to the collision theory, molecules act as small spheres that collide and bounce off each other, transferring energy among themselves when the collide. In order for a reaction to occur, there must be collisions between molecules. Through experimentation, factors are discovered that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, surface area, the physical state of reactants, and a catalyst. This experiment regarding the factors that affect reaction rate tests the effects of increased concentration and

Hypothesis: It was hypothesised the colder the water is, the slower the tablet dissolves and the hotter the water gets, the faster the tablet dissolves. This is due to the particles heating up and getting excited thus separating the particles faster. It was suspected that the 20°C tablet in water would finish dissolving at 6 minutes, the 40° would dissolve at 4 minutes and the 50° would dissolve at 2 minutes. Also it was suspected that the 30°C tablet in water would dissolve after 4 minutes and the 60°C would finish dissolving after 1 minute.

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.

The purpose of the experiment was to investigate the effect of the temperature of the water on the reaction of the tablet. There was a difference between the tablet in the cold water and the tablet in warm water. The tablet in cold water took 32.17 seconds to completely dissolve, and it took the tablet in warm water 26.67 seconds to completely dissolve. The hypothesis is that if one puts a tablet in cold water and one in warm water, then the water in cold water will take a longer time to dissolve and the tablet in the warm water will dissolve faster was supported. I got this result because the added energy in the hot water causes water molecules to move faster which make the tablet dissolve faster, and the tablet in colder water took a longer time because the cold water is condensed. This experiment relied on the temperature of the water how cold and how hot the water is. Perhaps this experiment could be improved by seeing the temperature of the water and how

After the experiment, I thought about and considered that if the rate of the reaction in which the alka seltzer tablet dissolves is related to the surface area, so by increasing the surface are it will increase the rate of reaction to when the tablet dissolves in the water. By timing the tablet has it dissolved with the water, the water began to fizz up. My hypothesis was proven correct how I said that the surface are of a half crushed tablet will dissolve faster, I had hypothesized right. It had been that the half crushed tablet had dissolved much faster then the other areas. By increasing the surface area the reaction rate of the tablet will dissolve much faster.

How does the temperature affect the speed in which an Alka-Seltzer tablet fully dissolves in three cups filled with water with different temperatures.

The antacid tablets were not crushed properly, resulting in big crumbs of the tablet which will affect the dissolving process of the lab.

can dissolve quickly in liquid. Thus, if exposed to rainwater, the pills would have dissolved. He will also show that

The results collected based on this experiment were to some degree surprising. I was surprised about the length of time it took for the beaker containing the cold water and Alka Seltzer tablet to dissolve. I predicted it would dissolve the slowest, however taking less time than it actually did, 2 minutes 43 seconds. I didn’t think it would take longer than 2 minutes for the Alka Seltzer tablet to dissolve. I wasn’t however surprised that the beaker containing hot water dissolved the tablet the fastest, as I had learnt that an increase in temperature increased the rate of

In this experiment it was observed that not all chemical reactions occur at the same rate. Chemical reactions occur when one or more substances are changed into other substances. The properties of a chemical reaction require three things. First, they need a source of energy for molecules to encounter each other. Second, they require to proceed at a steady rate. Third, they must proceed in a particular direction until they reach equilibrium. There are two types of chemical reactions that can occur: endergonic and exergonic reactions. In these reactions there are both reactants and products. In exergonic reactions the reactants (starting materials of a reaction) are higher than the products (results of a reaction). This is opposite for endergonic

An Alka Seltzer is a white, solid, odorless tablet that is used in our daily life. For the most part it is mainly used for temporary relief on heart burns, acid indigestion, upset stomachs, headaches and pain in general. The purpose of the lab conducted was to show the fastest way on can dissolve an alka seltzer tablet using different liquids. The liquids used were regular tap water, Sprite and Minute-Maid Apple Juice. So, if we use different types of liquids to see which will dissolve the alka seltzer the fastest, then out of the three liquids water will take the least amount of time to fully dissolve the tablet because it is the most recommended liquid to take with any

In this experiment, hydrochloric acids at different temperatures will be used to observe the effect of temperature in dissolving Alka Seltzer tablets. Four different temperatures as 25 degrees Celsius, 45 degrees Celsius, 65 degrees Celsius, and 85 degrees Celsius will be arranged before the experiment by using a heating pad. 25 degrees Celsius indicates the average room temperature and equal increases will be chosen to observe different responses of Alka seltzer to different temperatures.

Experimental Method: Polyethylene glycol 3350(PEG) was placed in water in order to measure the amount of time it took for the PEG to dissolve. The amount of both PEG and water were the same for each trial, the only changing factor was the temperature of the water. Timing started the moment PEG was placed into water, and the timer was stopped once PEG was dissolved.

On Thursday August 27, 2015 my group comprised of Elizabeth Cruz, Samantha St. Martin and I initiated experiment. This was constructed of three Alka-Seltzer tablets and three beakers containing different liquids: water, salt water, and vinegar. The drive behind our experiment was to see what factors would make the Alka-Seltzer tablets dissolve faster. My group’s hypothesis was that the strong chemical compounds in vinegar will cause the Alka-Seltzer to dissolve faster and therefore take the shortest amount of time compared to the other mixtures.

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
