Explanation:
(1) Sodalime is easy to handle because solid sodium hydroxide is corrosive in nature.
(2) Sodalime absorb less amount of water as compare to NaOH
In the decarboxylation reaction we use soda lime mixture.
sodalime is manufactured by mixing of NaOH and quick lime or calcium oxide i.e. CaO.
CH₃COONa + (NaOH + CaO) → CH₄ + Na₂CO₃+ CaO
Sodium acetate Sodalime Methane
in the decarboxylation reaction alkane is formed with sodium carbonate.
