Unit 8 Solutions, Acids, and Bases Review

The parts of a solution are the

• salt and vapor.
• solvent and solid.
• solute and water.
• solute and solvent.

In a solution, the solute is the substance that

• dissolves in the solvent.
• is in the greatest quantity.
• is the liquid.
• is a solid.

Sugar dissolves in water through

• ionization.
• dissocation.
• neutralization.
• dispersion.

A solution of hydrochloric acid in water is most likely to have a pH close to

• 14.
• 7.
• 12.

• 3.

Substances that form ions when dissolved in water are called

• solutions.
• molecules.
• polar.
• electrolytes.
