Question

Why is soda lime preferred to sodium hydroxide in the lab for preparation of methane? Can I write that it enhances the rate of the reaction?

Answer 1

Answer:

Decarboxylation of sodium salts of carboxylic acids by using soda lime to form alkanes is popularly known as Duma reaction. In this reaction sodium salts of carboxylic acid are heated with soda lime to form alkanes having one carbon atom less than the sodium salt of carboxylic acid.

Answer 2

Answer:

i hope it helps you

Explanation:

Decarboxylation of sodium salts of carboxylic acids by using soda lime to form alkanes is popularly known as Duma reaction. In this reaction sodium salts of carboxylic acid are heated with soda lime to form alkanes having one carbon atom less than the sodium salt of carboxylic acid.The solid sodium salt of a carboxylic acid is mixed with solid soda lime, and the mixture is heated. For example, if you heat sodium ethanoate with soda lime, you get methane gas formed: This reaction can be done with certain carboxylic acids themselves.
