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. Open a can of soda and measure the pH. Allow the open soda can to rest undisturbed on a level countertop at room temperature. 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? A. the pH of the soda B. the type of soda C. the temperature of the room D. the number of days

    The independent variable is independent and is not depended on another variable. The dependent variable is dependent on the independent variable and changes and that is the one that you measure in an experimental setting

    The independent variable is changing at a constant rate and that is why it is not dependent on the other

    The temperature of the room is not a factor in this experiment

    Yes it is A because the pH is dependent on the amount of days left out and the number of days is the independent variable
