Question

A saturated solution of a salt Z at 50 C is evaporated to dryness. If 50 g of the saturated salt solution was used 20.5 g of the residue was left behind. Calculate the solubility of the salt Z at 50 C.

Answer 1

Answer:

Here, at 50 °C, the solid solute obtained is = 50 gm

Since we had the saturated solution = 100 gm

It means there must be 50 gm of water in the saturated solution

Hence, the solubility of solute = (weight of solute in saturated solution/ weight of solvent in saturated solution ) x 100

So, at 50°C before the evaporation,

solubility =

50

50

×100 = 100

I dk cuz I have only asked question with another account lol
