Identify \(B\) in the following reaction \(\mathrm{H}_4 \mathrm{SiO}_4 \underset{-\mathrm{H}_2 \mathrm{O}}{\stackrel{1000{ }^{\circ} \mathrm{C}}{\longrightarrow}} A \underset{\Delta}{\stackrel{\text { Carbon }}{\longrightarrow}} B+\mathrm{CO}\)
- A corundum
- B quartz
- C silica
- D carborundum
Answer & Solution
Correct Answer
(C) silica
Step-by-step Solution
Detailed explanation
Orthosilicic acid \(\left(\mathrm{H}_4 \mathrm{SiO}_4\right)\), on heating at high temperature, loses two water molecules and gives silica \(\left(\mathrm{SiO}_2\right)\) which on reduction with carbon gives carborundum \((\mathrm{SiC})\) and \(\mathrm{CO}\).…
