Solution
Neutralization reaction and a precipitation reaction
- Neutralization reaction: “is a double decomposition reaction in which acid neutralizes a base and salt and water is formed.”
\[\ce{\underset{\text{Base}}{NaOH} + \underset{\text{acid}}{HCl}->\underset{\text{salt}}{NaCl} + \underset{\text{water}}{H2O}}\] - Precipitation reaction: “is a double decomposition reaction in which one product is ppt.”
\[\ce{\underset{\text{ferrous sulphate}}{FeSO4} + \underset{\text{sodium hydroxide}}{2NaOH}->Na2SO4 + \underset{\text{ppt. direct green}}{Fe[OH]2 v}}\]
