What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction and typically has a sour taste. Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a chemical reaction. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is a neutralization reaction?

Back

A neutralization reaction occurs when an acid reacts with a base to produce water and a salt.

Front

What is the formula for hydrobromic acid?

Back

The formula for hydrobromic acid is HBr.

Front

What is the hydronium ion?

Back

The hydronium ion (H3O+) is formed when an acid donates a proton to water.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base accepts a proton.

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton.
