If 180 grams of potassium iodide is dissolved in 100 cm3 of water at 30oC, a(n) _______________ solution is formed.
olga nikolaevna [1]

Super saturated solution is formed.

<u>Explanation:</u>

Solubility is the property of any substance's capacity, that is the solute of the substance is dissolved in the given solvent to form the solution. We have three different types of solution, unsaturated, saturated and supersaturated solution.

  • Unsaturated solution is a solution with lesser amount of solute than its solubility at equilibrium.
  • Saturated solution is a solution with the maximum solute dissolved in the solvent.
  • Super saturated solution is a solution with more solute than it is required.

The solubility of KI at 30°C is 153 g / 100 ml. Here 180 g of KI in 100 ml of water at 30°C is given, which has more solute than required, so it is super saturated solution.
