You are asked to perform a reaction by dissolving hypochlorous acid in water. Based on your understanding of acids, you understa
nd that hypochlorous acid dissolves in water to form hydronium ions and hypochlorite ions. You then write out the equation:
HOCl + H2O ⇋ H3O⁺ + OCl⁻

A saturated solution is one in which no more solute is able to dissolve in a given solvent at a particular temperature. Some amount of the solute is left undissolved in the solution.
Unsaturated solution has solute in lower proportions than required to form a saturated solution.
Supersaturated solution has solute in amounts greater than a saturated solution.
We can take the help of solubility curve in order to find out the amount of a salt required to prepare a saturated solution of that salt at a particular temperature.
The solubility of KI at 10 is 136 g/ 100 mL water
The solubility of at
is 21 g/100 mL water.
The solubility of at
is 80 g/100 mL water.
The solubility of NaCl at is 38 g/ 100 mL water.
So the correct answer will be KI, as it would need 136 g KI / 100 mL water to form a saturated solution at .So, if we have 80g KI/ 100mL water it would be an unsaturated solution.
