The measured freezing point depression of a non-volatile solute in aqueous solution is 0.20^(@) C . The elevation in boiling point of the same solution will be [ K_(f) = 1.86 K/m, K_(b) = 0.52 K/m]

depression in freezing point of 0.01 molal aqueous CH_(3)COOH solution is 0.02046^(@)C . Assuming molality equal to molarity. pH of CH_(3)COOH solution is (K_(f)=1.86K Kg "mol"^(-1)) _______________________.

In a 2.0 molal aqueus solution of a weak acid HX the degree of disssociation is 0.25. The freezing point of the solution will be nearest to: ( K_(f)=1.86 K kg "mol"^(-1) )
