Solubility

What is the solubility of AgBr in a) mol/L7.1 x 10-7 mol/Lb) g/100 mL1.3 x 10-5 g/L

Solubility

Which is more soluble: BaF2 OR CaSO4?BaF2 : 1.8 x 10-2 mol/L

CaSO4 : 7.8 x 10-3 mol/L

Therefore BaF2 is more soluble

Temperature and solubility

ΔHsol’n for NaNO3 = 35 kJ/molΔHsol’n for KOH = -56 kJ/mol

What happens to the solubility of each as temperature increases?
