1.0 molal aqueous solution of an electrolyte X_(3)Y_(2) is 25% ionized. The Boiling point of the solution is (K_(b) of H_(2)O=0.52K kg mol^(-1))
Elevation in p.b of a molar glucose solution (d=1.2g mL^(-1)) is :
The elevation in boling point of an aqueous solutions of NaCl is 0.01 .^(@) C . If its van't Hoff factor is 1.92 ,the molality of NaCl solution is ( K_(b) for water = 0 . 52 k kg mol^(-1) )
If aqueous solution contains 9% and 1% (W//W) of two non- volatile non- electrolytes X (molecular weight 180) and Y (mulecular weight 50 ) respectively the boiling point of solution in .^(@)C approximately is (k_(b) = 0.52 kg mol^(-1))
An aqueous solution of H_(2)O_(2) is purified by
Molality of an aqueous solution that produces an elevation of boiling point of 1.00K at 1 atm pressure (K_(b) for water =0.512K.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)
In aqueous solutions, H_(2)O_(2) oxidises H_(2)S to
