A Nashville State Biology I student wants to determine if the type of acidic solution impacts the effectiveness of the antacid. The student uses Coke and Diet Coke as the acidic solutions. Then adds 1 gram of Tums antacid to 200 mL of each solution. The student measures the pH before and after adding the antacid. The independent variable in this experiment is the _____

students are designing an experiment to see if changes in ph have an impact on the action of enzymes. which is the best hypothesis? will acidic ph reduce enzyme action? the ph and the temperature of the solution will have an effect on the reaction. a change in ph will change enzyme activity. a ph of 10 will result in less enzyme activity compared to ph 7

A curious CHE 1131 student purchased a can of soda water from the cafeteria. Upon opening the can and taking a sip, student noticed a tart taste indicating an acidic solution. The content of the soda water revealed it contained only water and carbonation. If the pressure in the can is 2.6 atom, provide reactions that accounts for this acidity and determine the concentration of the source of the acidity and find the pH by writing appropriate reactions.

Shakita wants to know if the pH of an open can of soda changes over time. To test this, she designs an experiment that will involve the following steps: 1. Open a can of soda and measure the pH. 2. Allow the open soda can to rest undisturbed on a level countertop at room temperature. 3. Measure the pH of the open soda can every day at the same time for ten consecutive days. What is the dependent variable in Shakita's experiment?
