Question

11.When 100g of a saturated solution is evaporated at 500C, 50g of solid is left over. Find the solubility of the substance at 500C.​

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 = 5050×100 = 100 

Answer 2

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
