Buffer
a weak acid or base in solution that resists changes in pH when a moderate amount of either an acid or base is added.
Indicator
a substance that changes color in the presence of an acid or base.
Neutralization
a double- replacement reaction between an acid and a base that produces a salt and water.
pH
a unitless number between 0 and 14 that tells how acidic or basic a substance is.
Acid
a substance that produces hydrogen ions in an aqueous solution.
Salt
an ionic compound formed by a combination of cations and anions.
Hydroxide ion
an ion formed by oxygen and hydrogen.
Aqueous solution
a water- based solution.
base
a substance that produces hydroxide ions in an aqueous solution.
