Identify correct statements from the following:
i. \(\mathrm{H}_3 \mathrm{BO}_3\) is a monobasic acid.
ii. The correct formula of borax is \(\mathrm{Na}_2\left[\mathrm{~B}_4 \mathrm{O}_5(\mathrm{OH})_3\right] 8 \mathrm{H}_2 \mathrm{O}\).
iii. \(\mathrm{NaBH}_4\) is a reducing agent.
- A i, ii, iii
- B i, ii only
- C ii, iii only
- D i, iii only
Answer & Solution
Correct Answer
(D) i, iii only
Step-by-step Solution
Detailed explanation
The explanations of given statements are as follows : (i) \(\mathrm{H}_3 \mathrm{BO}_3\) is a monobasic acid because in aqueous solution, it coordinates with a molecule of water to form a hydrated species, \(\mathrm{B}^{3+}\) ion pulls the \(\sigma\)-electron charge of…
