pH Scale Flashcard

Front

What is the pH scale?

Back

The pH scale is a measure of how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does a pH less than 7 indicate?

Back

A pH less than 7 indicates that the solution is acidic.

Front

What does a pH greater than 7 indicate?

A pH greater than 7 indicates that the solution is basic.

Front

What is a neutral pH value?

Back

A neutral pH value is 7, which is the pH of pure water.
