This page provides basic exercises in relating properties of acidic/basic solutions. When you press "New Problem', you will be asked to relate one property of a solution to another. For example, "What is the pH if the pOH = 2.34?" Determine the value of the answer, enter it in the answer cell and press "Check Answer". If you use scientific notation, make certain you follow the "e" convention. Thus, 2.3 × 10-4 would be entered 2.3e-4.
