Question

30 g of potassium chloride can be dissolved in 40 g of water at 50 degree celsius. What is the solubility of potassium chloride at this temperature?

Answer 1

Explanation:

Answer The solubility of potassium chloride at the given temperature is 32.4 g/100 g

Explanation:

Solubility is defined as the amount of solute that can be dissolved in 100 grams of solvent.

We are given:

Amount of potassium chloride dissolved in 30 grams of water = 9.72 g

To calculate the mass of potassium chloride that can be dissolved in 100 g of water, we use unitary method:

In 30 grams of water, amount of KCl dissolved is 9.72 grams

So, in 100 grams of water, amount of KCl dissolved will be =

Hence, the solubility of potassium chloride at the given temperature is 32.4 g/100 g
