Chemical Reactions, Reaction Rates, pH Scale

Front

What ions do acids release in water?

Back

Acids release positively charged hydrogen ions (H+) in water.

Front

What is the pH of a strong acid?

Back

A strong acid typically has a pH of less than 3.

Front

What does a pH of 7 indicate?

Back

A pH of 7 indicates a neutral solution, neither acidic nor basic.

Front

How does increasing concentration affect reaction rates?

Back

Increasing the concentration increases the speed of a reaction by increasing collisions between reactants.

Front

What is the pH scale used for?

Back

The pH scale measures the strength of acids and bases.

Front

What is a neutralization reaction?

Back

A neutralization reaction is when an acid and a base combine to form a salt and water.

Front

What is the pH range for acids?

Back

The pH range for acids is from 0 to 6.9.

Front

What is the pH range for bases?

Back

The pH range for bases is from 7.1 to 14.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH of the solution decreases (becomes more acidic) when an acid is added.

Front

What happens to the pH of a solution when a base is added?

Back

The pH of the solution increases (becomes more basic) when a base is added.
