Question

The equation for the preparation of \[C{H_4}\] from anhydrous sodium ethanoate [sodium acetate] is:
\[C{H_3}COONa + NaOH\xrightarrow{{CaO/\Delta }}C{H_4} + N{a_2}C{O_3}\]
A. True
B. False

Answer 1

Hint: Methane is conveniently prepared by heating an intimate mixture of anhydrous sodium acetate and Sodium hydroxide. This synthesis description was provided by Fritz Haber.

Complete Step-by-Step answer:
For the preparation of methane, these two compounds are used as reactants. Sodium acetate is used in the anhydrous form and is reacted with sodium hydroxide. Both these reactants are placed in a test tube and heated over a flame. Methane gas would soon start to evolve. This gas can now be collected separately. Also, it results in the formation of sodium carbonate. Representing the above process in a chemical reaction:
\[C{H_3}COONa + NaOH\xrightarrow{\Delta }C{H_4} + N{a_2}C{O_3}\]
The reaction given to us in the question involves the introduction of calcium oxide as a catalyst, which is not required for this process. Hence the give reaction is false.

Hence, Option B is the correct option.

Note: Ethanoate or sodium acetate is the sodium salt of acetic acid. This compound is available in a white granular powder. Also, sodium acetate is easily soluble in water. On the other hand, sodium hydroxide is a strong base. It is also known as caustic soda. It exists in the form of a white solid ionic compound.
