Front

What can cause chemical burns?

Back

Both acids and bases can cause chemical burns.

Front

What is the pH scale?

Back

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

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor basic.
