pBlock ElementsII 1 Question 26
26. For $\mathrm{H}{3} \mathrm{PO}{3}$ and $\mathrm{H}{3} \mathrm{PO}{4}$, the correct choice is
$(2003,1 M)$
(a) $\mathrm{H}{3} \mathrm{PO}{3}$ is dibasic and reducing
(b) $\mathrm{H}{3} \mathrm{PO}{3}$ is dibasic and non-reducing
(c) $\mathrm{H}{3} \mathrm{PO}{4}$ is tribasic and reducing
(d) $\mathrm{H}{3} \mathrm{PO}{3}$ is tribasic and non-reducing
Show Answer
Solution:
- $\mathrm{H}{3} \mathrm{PO}{3}$ is a dibasic, reducing acid. $\mathrm{H}{3} \mathrm{PO}{4}$ is tribasic, non-reducing acid.
Dibasic, reducing
Tribasic, non-reducing
