Acids Bases and Salts

Front

What is an acid?

Back

A substance that donates protons (H+) in a solution, resulting in a pH less than 7.

Front

What is a base?

Back

A substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution, resulting in a pH greater than 7.

Front

What is a neutral solution?

Back

A solution with a pH of exactly 7, indicating a balance between acids and bases.

Front

What is the pH scale?

Back

A scale ranging from 0 to 14 used to measure the acidity or basicity of a solution.

Front

What is the pH range of acids?

Back

Less than 7.

Front

What is the pH range of bases?

Back

Greater than 7.

Front

What is a salt?

Back

A compound formed from the positive ions of an acid and the negative ions of a base.

Front

What is an indicator?

Back

A substance that changes color in response to the pH of a solution, used to determine acidity or basicity.

Front

What is a neutralization reaction?

Back

A chemical reaction between an acid and a base that produces a salt and water.

Front

What is a strong acid?

Back

An acid that completely dissociates in water, resulting in a high concentration of H+ ions.
