Question

Choose ALL TRUE statements 1) A saturated solution is very unstable 2) Gases are typically more soluble at a lower temperature 3) Solids are typically more soluble at a lower temperature 4) An unsaturated solution contains less than the maximum amount of dissolved solute EJ 5) A supersaturated solution contains more than the maximum amount of dissolved solute Save

Answer 1

   1: False

There is a dynamic equilibrium exists between rate of dissolution and rate of recrystallization in saturated solution. So, the saturated solution stable.

2: True

The solubility of gases increases with decreasing temperature.

3: False

The solubility of most solids increases with increasing temperature.

4: True

A solution containing less than the equilibrium amount of solute ( maximum dissolvable amount) is an unsaturated solution.

5: True

A supersaturation solution contains more than dissolved amount of salt.
