Question

1. for each of the following, determine whether the statement is true or false. for those that are false, write a brief sentence indicating the required correction.

a. a saturated solution of nacl(s) can be filtered to remove the dissolved solute.
b. liquids that do not dissolve in water, such as oil, are said to be immiscible with water.
c. pressure is a major factor in the solubility of solids, liquids, and gases in water.

Explanation:

a.

Filtration separates undissolved solids from a solution, not dissolved solute. So the statement is false. The correction is: A saturated solution of NaCl(s) cannot be filtered to remove the dissolved solute.

b.

Immiscible liquids do not dissolve in each other. Since oil does not dissolve in water, it is immiscible with water. So the statement is true.

c.

Pressure has a significant effect mainly on the solubility of gases in water, not on solids and liquids. So the statement is false. The correction is: Pressure is a major factor only in the solubility of gases in water, not solids and liquids.

Answer:

a. False. A saturated solution of NaCl(s) cannot be filtered to remove the dissolved solute.
b. True
c. False. Pressure is a major factor only in the solubility of gases in water, not solids and liquids.
