Question

AB_2 is 10 \% dissociated in water to A^2+ and B^- The boiling point of a 10.0 molal aqueous solution of AB_2is \_ \_ \_ \_ \_ \_ \_^ C . (Round off to the Nearest Integer). [Given : Molal elevation constant of water K_b=0.5 Kkg mol^-1boiling point of pure water (=100^ C)

Accepted Answer

Correct answer: 106. (106) AB_2 A^2++2B^- t=0a00 t= ta-a a 2a n_T=a-a +a +2a =a (1+2 ) so, i=1+2 Now T_b=i m K_b T_b= (1+2 ) m K_b =0.1m=10K_b=0.5 T_b=1.2 10 0.5 =6 So boiling point =106

$AB_{2} is 10 % dissociated in water to A^{2 +} and B^{-} The boiling point of a 10.0 molal aqueous solution of AB_{2} is_______^{\circ} C . (Round off to the Nearest Integer). [Given : Molal elevation constant of water K_{b} = 0.5 Kkg mol^{- 1} boiling point of pure water (= 100^{\circ} C)$
