Chapter 8: Solutions

In order for a solution to form

• a solid must dissolve in a liquid

• the solvent must be water

• a gas must dissolve in a liquid

• • one substance must dissolve in another

During the formation of a solution, energy is

• neither released nor absorbed

• released only

• absorbed only

• • either released or absorbed

If you dissolve equal amounts of salt in warm water, room temperature water, and ice water

• the salt will dissolve most quickly in room-temp water

• the salt will dissolve most quickly in the ice water

• will dissolve most quickly in warm water

• None of the above

A solution that contains more solute than it would normally hold at a given temperature is said to be

• unsaturated

• supersaturated

• concentrated

• saturated

Which of the following is NOT a property of an acid?

• usually reacts with metal

• changes the color of an indicator

• feels slippery

• tastes sour

Which of the following is NOT a common property of bases?

• tastes bitter

• reacts with metals

• changes colors of indicators

• feels slippery

A base is defined as a compound that produces

• hydrogen ions in solution

• hydronium ions in solution

• sodium ions in solution

• hydroxide ions in solution

In order to calculate molarity of a solution, you need to know the moles of solute and the

• volume of the solution

• mass of the solution

• volume of the solute

• volume of the solvent

The maximum amount of solute that will dissolve in a solution at a given temperature is

• concentration

• degree of saturation

• rate of solution

• solubility

The rate of dissolving of a rock in a stream would be increased by all of the ollowing EXCEPT

• moving the rock to a faster-moving current

• moving the rock to warmer water

• reducing the exposure of the rock to water

• • breaking the rock into smaller pieces
