Front

What is pH?

Back

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

Front

What is an acid?

Back

An acid is a substance that releases H+ ions when dissolved in water.

Front

What is a base?

Back

A base is a substance that releases OH- ions when dissolved in water.

Front

What is a neutral solution?

Back

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

Front

What does a low pH indicate?

Back

A low pH (below 7) indicates a high concentration of H+ ions, meaning the solution is acidic.

Front

What does a high pH indicate?

Back

A high pH (above 7) indicates a high concentration of OH- ions, meaning the solution is basic.

Front

What is the pH of pure water?

Back

The pH of pure water is 7, which is considered neutral.

Front

What is the taste of acidic solutions?

Back

Acidic solutions typically taste sour.

Front

What is the taste of basic solutions?

Back

Basic solutions typically taste bitter.
