2 Solubility rules
Cl-, Br-, I- are soluble except with Ag+, Hg22+ and Pb+2.
Hydroxides (OH- ) are insoluble except those of Grp 1A, Sr+2, Ba+2, and Ca+2.
Nitrates (NO3-) are all soluble
Sulfates (SO42- ) are soluble except those of Sr+2, Ba+2 , Hg22+ and Pb+2.
Carbonates (CO32- ) are all insoluble except those of Grp 1A, and NH4+.

3 Solution and Concentration equations
Solution  Molarity = moles solute / Liters solution

Dilution : C1V1 = C2V2
Concentrations  Molarity = moles solute / Liters solution

w/v = g solute / ml solution w/w = g solute / g solution v/v = ml solute / ml solution
