Concept explainers
Interpretation:
To determine whether each o the following solutions will be saturated or unsaturated at 20oC.. by using the following table.
Solubility (g/100 g H2O) | ||
Solutions | 200C | 500C |
KCl | 34 | 43 |
NaNO3 | 88 | 110 |
C12H22O11(sugar) | 204 | 260 |
a. Adding 25g of KCl to 100 g of H2O.
b. Adding 11 g of NaNO3 to 25 g of H2O.
c. Adding 400g of sugar to 125 g of H2O.
Concept introduction:
Solubility: It is defined as the amount of a given substance that can be dissolved in the certain amount of solvent.
Depending upon the solubility and nature of solutions they can be divided into two types.
A saturated solution contains the maximum quantity of a solute that dissolves at that temperature.
An unsaturated solution contain less than the maximum amount of solute that can dissolves at a particular temperature.
