Boiling point of a liquid increases upon dissolving a non - volatile solute. Discuss.
Molal depression constant for water is 1.86 K.Kg. "mole"^(-1) . The freezing point of a 0.05 molal solution of a non electrolyte in water is
What is the influence of added non-volatile solute on the boiling point of solvent ?
The osmatic of solution containing non-volatile, non electrolyte solute is 7.6 atm at 27^(@)C then the boiling point of the same solution is _(Assume that molality and molarity are same)
The elevation in boiling point of a solution containing 0.20g of solute in 20g of ether is 0.17^@C , K_b for ether is 2.16 K kg/mol. Calculate the molar mass of solute.
When 36g of a non-volatile, non-electrolytic solute having the empirical formula CH_(2)O is dissolved in 1.2 kg of water, the solution freezes at -0.93^(@)C . The molecular formula of the solute is ( K_(f) of water = 1.86 K kg mol^(-1) )
Equal volumes of 1.0M AgNO_(3) and 1.0M KCl are mixed . The depression of freezing point of the resulting solution will be (K_(f)(H_(2)O)=1.86 K kg "mol"^(-1), 1M=1m)
A solution of sucrose (molar mass 342 "gmol"^(-1) ) has been produced by dissolving 68.5g sucrose in 1000g water. The freezing point of the solution obtained will be ( K_f for H_2O = 1.86 kg "mol"^(-1) )
