Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What does pH stand for?

Back

pH stands for 'potential of Hydrogen' and measures the acidity or basicity of a solution.

Front

What is the pH scale range?

Back

The pH scale ranges from 0 to 14, with 7 being neutral.

Front

What is a neutral substance?

Back

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

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in water, releasing all of its hydrogen ions.

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, releasing some but not all of its hydrogen ions.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in water, releasing all of its hydroxide ions.

Front

What is a weak base?

Back

A weak base is a base that partially dissociates in water, releasing some but not all of its hydroxide ions.
