Borax dissolves in water and forms a product of boron (X). Identify the compound \(\mathrm{X}\).
- A \(\mathrm{HBO}_2\)
- B \(\mathrm{B}_2 \mathrm{O}_3\)
- C \(\mathrm{NaBO}_2\)
- D \(\mathrm{H}_3 \mathrm{BO}_3\)
Answer & Solution
Correct Answer
(D) \(\mathrm{H}_3 \mathrm{BO}_3\)
Step-by-step Solution
Detailed explanation
\begin{aligned} & \text { Borax }=\mathrm{Na}_2 \mathrm{~B}_4 \mathrm{O}_7 \cdot 10 \mathrm{H}_2 \mathrm{O}=\mathrm{Na}_2\left[\mathrm{~B}_4 \mathrm{O}_5(\mathrm{OH})_4\right] \cdot 8 \mathrm{H}_2 \mathrm{O} \\ & \mathrm{Na}_2 \mathrm{~B}_4 \mathrm{O}_7 \cdot 10 \mathrm{H}_2…
