Question

state if the solubility increases, decreases or remains same on heating solution of calcium carbonate, potassium nitrate, sodium chloride ​

Answer 1

Answer:

• Solubility of Calcium Carbonate decreases on heating.

• Solubility of Potassium Nitrate increases on heating.

• Solubility of sodium chloride increases on heating .

Explanation:

• In an endothermic process, the solubility of solute increases with increase of temperature.

• In an exothermic process, the solubility increases on lowering the temperature.

• The amount of solute the dissolved in 100 grams of solvent to form a saturated solution at a particular temperature is called its solubility.

• The solubility of a solute in a particular solvent at a given temperature is equivalent to the maximum number of grams of the solute necessary to saturate 100 grams of the solvent at that temperature.

Answer 2
