Question

Part A Consider if the mixture is at. 60 degree C. To what extent will each solute be dissolved? Question Rank these KNO3 and K2SO4 as (1)Totally dissolved, (2) partially dissolved and (3) no dissolved Part B Crystallization is the opposite of dissolution. Since solids tend to dissolve better at higher temperatures, we can cause them to crystallize (i.e., undissolve) from a solution by lowering the temperature. Question If the solution described is cooled to 0 degree C , what mass of KNO3 should crystallize? Enter your answer numerically in grams.

Explanation / Answer

Both are totally dissolved
If you look at the graph for KNO3 the solubilty limit will be 15.0g per 100 g H2O scale that up to 130g H2O and get 19.5 g as the solubility limit. Subtract 19.5 from 35.7g (total mass present of KNO3) to get 16 g of KNO3 crystallizing.
