Front

Define pH.

Back

pH is a measure of the acidity or basicity of a solution, calculated as the negative logarithm of the hydrogen ion concentration.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

What does a pH value of 7 indicate about a solution?

Back

A pH value of 7 indicates that the solution is neutral.

Front

What is the pH range for acidic solutions?

Back

pH values less than 7.

Front

What is the pH range for basic solutions?

Back

pH values greater than 7.
