Q68 / 160 · JIPMER 2012 · Chemistry
Glauber's salt is
- Correct answerA$\mathrm{Na}_2 \mathrm{SO}_4 \cdot 10 \mathrm{H}_2 \mathrm{O}$
- B$\mathrm{Na}_2 \mathrm{~S}_2 \mathrm{O}_3 \cdot 5 \mathrm{H}_2 \mathrm{O}$
- C$\mathrm{CuSO}_4 \cdot 5 \mathrm{H}_2 \mathrm{O}$
- D$\mathrm{Na}_2 \mathrm{~B}_4 \mathrm{O}_7 \cdot 10 \mathrm{H}_2 \mathrm{O}$
Solution
$\begin{array}{l|l}
\text{Formula of compound} & \text{Name of compound} \\
\hline \mathrm{Na}_2 \mathrm{SO}_4 \cdot 10 \mathrm{H}_2 \mathrm{O} & \text{Glauber's salt} \\
\mathrm{Na}_2 \mathrm{~S}_2 \mathrm{O}_3 \cdot 5 \mathrm{H}_2 \mathrm{O} & \text{Hypo} \\
\mathrm{CuSO}_4 \cdot 5 \mathrm{H}_2 \mathrm{O} & \text{Blue vitriol} \\
\mathrm{Na}_2 \mathrm{~B}_4 \mathrm{O}_7 \cdot 10 \mathrm{H}_2 \mathrm{O} & \text{Borax}
\end{array}$
Hence, the correct answer is option: 'A'.
