1-True or False

The solubility of gases in liquids increases with increasing pressure.

2-True or False

An aqueous solution containing a nonvolatile solute such as sucrose will boil above 100°C at 1 atm pressure.

3-True or False

The solubility of KBr at 20°C is 60 g/100 g H2O. Increasing the temperature of the solution will likely increase the solubility of KBr.

Answer #1

Ans 1 : True

The solubility of gases in liquids increases with increasing pressure , as the particles are pushed into the liquid with larger force.

Ans 2 : True

When a non volatile substance is added to a solvent , the vapor pressure of the solution decreases. So more amount of energy is required to bring the solution to boil.

Ans 3 : True

Increasing the temperature increases the solubility of solute in the solution as high temperature increases the kinetic energy of molecules due to which collisions increase.
