A saturated solution of potassium chlorate is dissolved in 100g of water. If the saturated solution is cooled from 90 degrees Ce
dedylja [7]

Mass would crystallize out : 24 g

<h3>Further explanation </h3>

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility

  • 1. Temperature:
  • 2. Surface area:
  • 3. Solvent type:
  • 4. Stirring process:

We can use solubility graph to solve this.

solubility KClO₃ at 90°C=52 g

solubilty KCl₃ at 60°C= 28 g

Mass would crystallize out = 52 - 28 =24 g
