Question

The standard laboratory decarboxylation of sodium salts of carboxylic acids to yield alkanes utilizes 'soda lime'. What is the exact chemical composition and standard molar mixing ratio of soda lime?

Answer: C

💡 Solution & Explanation

Soda lime is a critical decarboxylating reagent prepared by intimately mixing Sodium Hydroxide ($NaOH$) and Calcium Oxide ($CaO$) in a fixed 3:1 ratio by mass/moles. It allows decarboxylation to proceed smoothly upon heating, converting $R-COONa$ into $R-H$ + $Na_2CO_3$.
