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?
