3 different solutions where made in the laboratory
a) 0.1 mole of sodium chloride in 100 mL of water (M.W.= 58.44 g/mol)
b) 0.1 mole of calcium chloride in 100 mL of water (M.W.= 110.98 g/mol)
c) 0.1 mole of ammonia in 100 mL of water (M.W.= 17.03)
Order the solutions in increasing freezing point (from lowest to highest). Show all your work.
Given : Three different compound ( Sodium chloride, Calcium chloride and Ammonia) with same mole and volume.
To find : increasing order of freezing points
Solution : As we know that, the freezing point also a physical property of compounds. Generally freezing point of compounds depends on the van't hoff factor of that substance or compound and concentration of compound. If the concentration is same then freezing point depend only van't hoff factor and that is directly proportinal to freezing point.
