Initial Activity- What mass of solute will dissolve in 100g of water at the following temperatures?
• KNO3 at 70°C =
• NaCl at 100°C=
• NH4Cl at 90°C=

Respuesta :

The mass of solute will dissolve in 100g of water at the following temperatures will be  153 gms, 40 gms, 70gms simultaneously.

How dissolution of solute is affected by temperature ?

On increasing temperature the amount of solute for dissolution decreases.

It is independent of the nature of solute.

Hence,

  • KNO₃ at 70degree = 153 gms
  • NaCl at 100 degree = 40 gms
  • NH₄Cl at 90 degree = 70gms
