Calculate the depression in the freezing point of water when 10g of `"CH"_(3)"CH"_(2)"CHClCOOH"` is added to 250g water. `K_(a)=1.4xx10^(-3),K_("f")=1.86" K kg mol"^(-1)`.

Calculate the depression in the freezing point of a solution containing 0.1 g of K_(3)[Fe(CN)_(6)] in 100 g of H_(2)O ? (molecular weigth of K_(3)[Fe(CN)_(6)]=329, K_(f)=1.86K " kg mol"^(-1) )

12.25 g of CH_(3)CH_(2)CHCICOOH is added to 250 g of water to make a solution . If the dissociation constant of above acid is 1.44xx10^(-3) the depression in freezing point of water in ""^(@)C "is" (K_(f) for water is 1.86 K kg "mol"^(-1))

1.2 mL acetic acid having density 1.06 g cm^(-3) is dissolved in 1 litre of water. The depression in freezing point observed for this concentration of acid was 0.041 ""^(@)C . The van't Hoff factor of the acid is ( K_(f) of water = 1.86 K kg mol^(-1) )

Calculate the pH of 0.01 M solution of CH_(3)COOH.K_(a) for CH_(3)COOH at 298K is 1.8xx10^(-5)

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)
