Salts:
* Sodium chloride (NaCl): Dissolves into Na+ (sodium ions) and Cl- (chloride ions).
* Potassium nitrate (KNO3): Dissolves into K+ (potassium ions) and NO3- (nitrate ions).
* Calcium carbonate (CaCO3): Dissolves slightly to form Ca2+ (calcium ions) and CO32- (carbonate ions).
Acids (other than strong acids like HCl, HNO3, H2SO4):
* Acetic acid (CH3COOH): Ionizes partially to form H+ (hydronium ions) and CH3COO- (acetate ions).
* Carbonic acid (H2CO3): Ionizes to form H+ (hydronium ions) and HCO3- (bicarbonate ions).
Bases (other than strong bases like NaOH, KOH):
* Ammonia (NH3): Reacts with water to form NH4+ (ammonium ions) and OH- (hydroxide ions).
Other ionic compounds:
* Magnesium sulfate (MgSO4): Dissolves into Mg2+ (magnesium ions) and SO42- (sulfate ions).
* Copper(II) chloride (CuCl2): Dissolves into Cu2+ (copper(II) ions) and Cl- (chloride ions).
Important Note: The extent of ionization depends on the specific substance and its concentration. Some substances are strong electrolytes and ionize completely in water, while others are weak electrolytes and only ionize partially.
