For which salt, K2SO4, Li2SO4, KClO4, or NH4Cl, will increasing the temperature of the water have the greatest change in solubility per 100 g solvent?

Answer 1

Don't you have a graph or a table that gives you solubility at various temperatures?

Answer 2

Correct
You can estimate the slopes qualitatively by looking to see which line is the steepest. You could also calculate values by finding Δy/Δx. If you do this, you should have calculated values approximately equal to the following:
Salt Slope
Li2SO4 −0.07
K2SO4 0.13
KClO4 0.17
NH4Cl 0.47

Answer 3

NH4Cl is the answer
