Weak electrolyte

Partially ionizes in water.

Strong electrolyte

Completely ionizes or dissociates in water.

Non-electrolyte

Does not form ions in water.

Brønsted-Lowry acid:

Donates a proton (H⁺).

Brønsted-Lowry base

Accepts a proton (H⁺).

Weak acid

Partially ionizes in water.

Weak base

Partially reacts with water to accept H⁺.

Strong acid/base

Completely ionizes (acid) or dissociates/reacts essentially completely (base) in water.

Net ionic equation

Shows only the species that participate in the reaction.

Limiting reactant

Reactant that runs out first.

Yield

Amount of product obtained.

Theoretical yield

Maximum product possible from the limiting reactant.

Titrant

Solution of known concentration added during titration.

Standard solution

Solution with a precisely known concentration.

Standardize

Determine a solution's exact concentration.

Analyte

Substance being measured in a titration.

Titration error

Difference between the measured result and the true or accepted value.

Primary standard

Highly pure, stable substance used to determine a solution's concentration.

Hydrolysis

Reaction of a substance with water that can produce ions and affect pH.
