Specification Point 2.38:
Know that metal Oxides, Metal Hydroxides and Ammonia can act as bases, and that alkalis are bases that are soluble in water
Oxides, Metal Hydroxides & Ammonia
Alkali: Bases that are soluble in water and dissolves to form hydroxide ions OH–
The pH of Bases (Alkali)
Metal Oxides can act as a base and is soluble in water
Metal Oxide + Acid → Salt + Water
Example: Metal Hydroxides
Metal Hydroxides can act as a base and is soluble in water
Metal Hydroxide + Acid → Salt + Water
Ammonia can act as a base and is soluble in water
Ammonia + Acid → Salt + Water
