Solubility of Salts

Solubility of Salts

  1. Solubility is the ability of a compound to dissolve in a solvent.
  2. Table below shows the solubility of the salts of nitrate, sulphate, chloride and carbonate.

Salt Solubility
Salt of potassium, sodium and ammonium All soluble in water
Salt of nitrate All soluble in water
Salt of sulphate Mostly soluble in water except:
(Pb) Lead sulphate
(Ba) Barium sulphate
(Ca) Calcium sulphate
Salt of chloride Mostly soluble in water except:
(Pb) Lead chloride
(Ag) silver chloride
(Hg) mercury chloride
Salt of carbonate Mostly insoluble in water except:
Potassium carbonate
Sodium carbonate
Ammonium carbonate

Notes:
Lead halide such as lead(II) chloride (PbCl2), lead(II) bromide (PbBr2) and lead (II) iodide (PbI2) are insoluble in cold water but soluble in hot water.

Solubility of oxide and hydroxide

Oxide and Hydroxide Solubility
Oxide Mostly insoluble in water except: K2O and Na2O.
Hydroxide Mostly insoluble in water except: KOH and NaOH
