Acid and bases

What defines an acid in chemistry?

An acid is a substance that donates protons (H+) in a chemical reaction, typically having a pH less than 7.

What defines a base in chemistry?

A base is a substance that accepts protons or donates hydroxide ions (OH-) in a chemical reaction, typically having a pH greater than 7.

What is pH?

pH is a measure of how acidic or basic a solution is, on a scale from 0 to 14.

What is the pH range of acids?

Acids typically have a pH range from 0 to 6.9.

What is the pH range of bases?

Bases typically have a pH range from 7.1 to 14.

What is neutralization?

Neutralization is the chemical reaction between an acid and a base, resulting in the formation of water and a salt.

What are some common uses of acids?

Acids are used in batteries, food preservation, and cleaning products.

What are some common uses of bases?

Bases are used in soaps, detergents, and as antacids.

What is the Arrhenius theory?

The Arrhenius theory states that acids produce H+ ions in solution while bases produce OH- ions.

What is a strong acid?

A strong acid is one that completely ionizes in solution, such as hydrochloric acid (HCl).
