What will be the concentration of a solution which is made by dissolving 36 gram of sodium chloride in hundred gram of water?

(a) To make a saturated solution, 36g of sodium chloride is dissolved in 100g of water at 293 K. Find its concentration at this temperature.

(a) Mass of solute = 36 g

     Mass of solvent = 100g

     Mass of solution = 100 + 36

                            = 136g

Concentration of solution = (Mass of solute / Mass of solution ) x100

                                   = (36/136) x 100

                                   = 26.47%

(b) If temperature increases, solubility increases and if temperature decreases, solubility decreases.

(c) Because particle size is bigger in suspensions hence it is easier to distinguish the particles of solute.
