Acids, Bases, and Solutions

How is a solute different from a solvent in a solution?

• The solute is present in a smaller amount.

• The solute is present in a greater amount.

• The solute is a solid and the solvent is a liquid.

• The solute is a liquid and the solvent is a gas.

Weak tea is an example of a

• dilute solution.

• concentrated solution.

• suspension.

• solvent.

Which is a characteristic property of acids?

• They turn blue litmus paper red.

• They turn red litmus paper blue.

• They taste bitter.

• They do not react with metals.

A liquid mixture in which particles can be seen and easily separated by settling or filtration is a

• solution.

• suspension.

• solvent.

• solute.

When you add so much solute that no more dissolves, you have a(n)

• saturated solution.

• unsaturated solution.

• neutralization.

• suspension.

When a solid compound dissolves in water,

• it breaks up into individual crystals.

• it always conducts electricity.

• its particles surround individual water molecules.

• each of its particles becomes surrounded by water molecules.

Neutralization is a reaction between a(n)

• acid and a base.

• acid and a metal.

• base and a salt.

• salt and water.

What is one way to increase the solubility of sugar in water?

• Heat the water.

• Chill the water.

• Increase the amount of sugar.

• Decrease the amount of water.

How can a scientist safely tell whether an unknown solution is salt in water or sugar in water?

• by tasting the solution

• by smelling the solution

• by testing the electrical conductivity of the solution

• by filtering the solution

In a water solution, how do acids differ from bases?

• Acids form hydrogen ions (H⁺), while bases form hydroxide ions (OH^-).

• Acids turn litmus blue, while bases turn litmus red.

• Acids form salts, but bases do not.

• Hydrogen ions (H⁺) remain dissolved, but hydroxide ions (OH^-) do not.
