Ch. 6 Acids, Bases, + 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 neutral

• base and a salt

• salt and 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 paper blue, while bases turn litmus paper red

• acids form salts, but bases do not

• hydrogen ions (H+) remain dissolved, but hydroxide ions (OH-) do not
