Which one of the following elements reduces \(\mathrm{NaOH}\) to \(\mathrm{Na}\) ?
- A \(\mathrm{Si}\)
- B \(\mathrm{Pb}\)
- C \(\mathrm{C}\)
- D \(\mathrm{Sn}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{C}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{NaOH}\) when heated with coke, gets reduced to Na. \(6 \mathrm{NaOH}+2 \mathrm{C} \stackrel{\Delta}{\longrightarrow} 2 \mathrm{Na}+2 \mathrm{Na}_2 \mathrm{CO}_3+3 \mathrm{H}_2 \uparrow\) Here, C behaves as reducing agent.
