10 kg of saturated solution of a highly soluble component a at 80°c is cooled to 30°c calculate the amount of an-hydrous crystals are coming out of the solution solubility of a at 80*c is 0.8 kg of a 1 kg of water and at 30°c is 0.3 kg of a 1 kg of water a) 2.73 kg b) 5.73 kg c) 4.73 kg d) 3.73 kg

The amount of anhydrous crystal are coming out of the solution when this is cooled from 80°C to 30°C are 5 kg of A

Explanation:

A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent, and knowing the solubility of component A at 80°C it is possible to know their amount, thus:

10Kg of water × = 8 kg of A

The maximum concentration that water can dissolve at 30°C is:

10Kg of water × = 3 kg of A

Thus, the amount of anhydrous crystal are coming out of the solution when this is cooled from 80°C to 30°C are:

8 kg of A - 3 kg of A = 5 kg of A

I hope it helps!
