1. henry's law

   • Sg =kPg
     • Sg---> solubilty of gas
     • Pg-----> partial pressure of gas
     • k-->Henry's law constant
       • k--->Henry's law constant

2. Raoult's law

   • ra
   • Pa=XaP°a
     • P°a-->vapor pressure of the pure solvent
     • Xa-->mole fraction of solvent
     • Pa-->vapor pressure of solution

3. boiling point

   • dT=Kb.m
     • m-->molality
     • Kb-->molal boiling point elevation constant
     • dT-->change in boiling point
       • it' added to the normal boiling point of the solvent

4. freezing point

   • dTf=Kf.m
     • m-->molalityof the solution
     • Kf-->freezing point constant
     • dTf--> change in freezing point
       • it's subtracted from the normal freezing point of the solvents
