Sodium bicarbonate - NaHCO3 - baking soda
Magnesium sulfate - MgSO4 - epsom salts
Calcium sulfate - CaSO4 - gypsum
Potassium chloride - KCl - sold in supermarkets as a salt substitute
Calcium chloride - CaCl2 - some ice-melting salts
Sodium hydroxide - NaOH - lye

In garden centers you will probably be able to find salts containing
ions like ammonium, nitrate, phosphate, etc.
