Question

44) Which compound of silicon is used for the preservation of eggs

Answer 1

Part I - Compound of silicon used for preservation of eggs

Sodium silicate $\left({\mathrm{Na}}_2{\mathrm{SiO}}_3\right)$ is used for the preservation of freshly laid eggs, by immersing them in the solution of sodium silicate.

Part II - Reason why sodium silicate is used for preservation

Sodium silicate is used because it increases the shelf life of freshly laid eggs by forming a layer of sodium silicate on the eggs, and hence makes them viable for a longer period of time
