NaOH is formed according to the reaction
\(2 \mathrm{Na}+\frac{1}{2} \mathrm{O}_{2} \rightarrow \mathrm{Na}_{2} \mathrm{O}\)
\(\mathrm{Na}_{2} \mathrm{O}+\mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{NaOH}\)
To make 4g of NaOH, Na required is
\(2 \mathrm{Na}+\frac{1}{2} \mathrm{O}_{2} \rightarrow \mathrm{Na}_{2} \mathrm{O}\)
\(\mathrm{Na}_{2} \mathrm{O}+\mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{NaOH}\)
To make 4g of NaOH, Na required is
- 4.6g
- 4.0g
- 2.3g
- 0.23g
Answer
(C) 2.3g
