Carrie is performing an experiment on acids and bases, so she forms the following hypothesis: If an acidic solution is added to a basic solution, the pH of the resultant solution will decrease. What is the dependent variable in Carrie's experiment?
The independent variable is the amount of acidic solution added.
The dependent variable is the value of the pH.
The independent variable is the amount of acidic acid added to the basis solution.
The concentration of the acid should remain the same, The type of acid added should be the same as well as the type, concentration, and volume of the basic solution should remain the same. These are constants that are to remain the same.
The dependent variable is the resulting pH values.
The volume of acid added can be graphed on the x axis and the value of pH on the y axis.
