Neutralization → occurs when acid reacts with base to form a salt and water. Base can be metal oxide or metal hydroxide.
H+ ions from acid react with O2- ions from the metal oxide or OH- ions from metal hydroxides, forming water molecules, H2O. Resulting mixture - neutral.
Base + acid = salt + water
Examples:
Magnesium oxide + dilute sulfuric acid → magnesium sulfate + water
MgO(s) + H2SO4 (aq) →MgSO4 + H2O (l)
copper (II)hydroxide + dilute nitric acid → copper(II)nitrate + water.
Cu(OH)2(s) + 2HNO3(aq) → Cu(NO3)2(aq) + 2H2)(l)
- Surfaces of copper objects become tarnished as they react with oxygen in the air from copper(II)oxide.
- copper(II)oxide → based on reactions with acids.
List of neutral oxides (do not form any salt):
- Nitrous oxide
- Nitric oxide
- Carbon monoxide
- Water
When an acid reacts with aqueous ammonia ⇒ an ammonium salt is formed. example: → → no water is formed in this process though
Ionic Equation for reaction between Acid and Base is:
