Titrations

Acid

A water-soluble compound capable of donating protons (H⁺ ions) to another substance.

Analyte

A substance that is being investigated.

Base

A water-soluble chemical compound that is able to accept protons (H⁺ ions).

Dissociate

To break up into smaller components.

Equivalence point

The point in a titration where there are equivalent amounts of titrant and analyte so the two substances can react completely with nothing left over.

Indicator

A substance that changes color when in contact with an acid or base.

Litmus paper

A paper coated with an indicator called litmus.

Molarity

A measure of concentration equal to moles per liter.

Neutralize

To make an acidic or basic solution chemically neutral.

pH

A measure of the concentration of hydrogen ions [H⁺] in a solution.

Strong acid

An acid that has a relatively high degree of dissociation in water.

Strong base

A base that has a relatively high degree of dissociation in water.

Titrant

A substance of known composition and concentration that is used to react with an analyte.

Titration

A process in which a chemical reaction is used to measure the concentration or to determine the identity of a solution.

Titration curve

A graph of a titration in which the amount of titrant is recorded on the x-axis to determine the identity of a solution.

Weak acid

An acid that has a relatively low degree of dissociation in water.

Weak base

A base that has a relatively low degree of dissociation in water.
