Front

What ion is more present in a basic solution?

Back

OH- (hydroxide ion)

Front

What do acids produce when dissolved in water?

Back

Hydrogen ions (H+)

Front

What is the pH of pure water?

Back

7 (Pure water is a neutral substance)

Front

What does pH measure?

Back

The concentration of H+ ions (hydrogen ions)

Front

Which pH value indicates a stronger acid?

Back

pH 1 is a stronger acid than pH 4, pH 8, or pH 13.

Front

What is an acid?

Back

A substance that donates hydrogen ions (H+) in a solution.

Front

What is a base?

Back

A substance that accepts hydrogen ions (H+) or donates hydroxide ions (OH-) in a solution.

Front

What is the pH scale range?

Back

0 to 14, where 7 is neutral, below 7 is acidic, and above 7 is basic.

Front

What happens to the pH when an acid is added to water?

Back

The pH decreases (becomes more acidic).

Front

What happens to the pH when a base is added to water?

Back

The pH increases (becomes more basic).
