Question- We usually assume that salts as iron III sulfate, Fe2(SO4)3, dissociate completely when they dissolve in water. However, this is not always the case. What percent of the Fe2(SO4)3 actually dissociates in water if the freezing point of a 0.105 m solution of this salt in water is -0.625C degree? The proportionality constants for h20 are Kf= 1.86 and kb =0.515 Can you help me out with solving this problem?
Please illustrate work if possible thanks
