Factors That Affect The Heat Of An Antacid Tablets Lab

Use ice if you need to. Then, fill one beaker with 175 mL of water and the other with 350 mL. Warm the water in the 350mL beaker up to 55 degrees celsius and cool the water in the 175mL beaker to 15 degrees celsius, the same temperature as the pitcher because it will be your control group. Once the beaker that should be heated is at 55 degrees celsius, pour 175 mL of the water into a glove and pour the other 175 mL into a ziplock baggie. Pour the 15 degrees celsius, 175 mL of water into another ziplock baggie. Before you set these in water, have a stopwatch ready and make sure that the water in the baggies and glove is at the right temperature.

Step 3: Use the thermometer to identify and record the temperature for room temperature, in your refrigerator, in your freezer, and then research the temperature of boiling water (do not take this temperature) and record them in Table 2.

27. Heat the water to 40°C with an alcohol lamp by setting up the apparatus as shown in figure 3 below:

Hypothesis: If the temperature of the sodium thiosulfate is increased, then the time it takes the precipitate to form will decrease therefore leading to the rate of reaction to increase as well. This can be explained as the temperature increases, the particles in the molecule will be moving more rapidly and hence as they move quicker, they will be colliding with other particles more frequently and with more energy. This energy will likely overcome the activation energy barrier and break the initial bonds and therefore produce a successful reaction and due to the increase in frequency of collisions, the time it takes the precipitate to form will decrease and since the product/precipitate is produced faster, therefore the rate of reaction will increase.

Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working.

As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease.

Put 1 cup of cold water in one cup and 1 cup warm water in the other cup

Question: How does changing enzyme concentration or temperature affect the reaction time of enzyme activity?

8. I added the 3 ml of soap to the beaker and stirred the solution 40-50 times with a fresh pipette.

9. The stop watch was stopped once the “X” was no longer visible and obscured by the now opaque liquid solution.

The hypothesis tested in this experiment was, if the temperature of enzyme catalysis were increased, then the reaction rate would increase, because enzyme-catalysis reacts by randomly colliding with substrate molecules, and the increase in temperature increases the speed of collision or reaction rate. The final data collected for the experiment was positive with my hypothesis. The coffee filter, covered in potato solution, sank and rose at a faster pace in the hydrogen peroxide when the temperatures were raised.

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

XIII. Carefully remove the copper metal from the filter paper onto the watch glass. (with a spatula) Place a 400 ml beaker on a hot plate contained with water. Carefully place the watch glass before the water boils to dry the copper metal. (Use the tongs to handle the hot watch glass)

reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow

The styrofoam cups were used to store the acid (cup was labeled A) and base (cup was labeled B) prepare for them to be mixed. A lid was put on cup A and then the temperature probe was inserted to begin to measure the temperature
