Question

Urea reacts with water to form \(A\) which will decompose to form \(B\). \(B\) when passed through \(C u^{2+}(a q)\), deep blue colour solution \(\mathrm{C}\) is formed. What is the formula of \(\mathrm{C}\) from the following
A \(\mathrm{CuSO}_{4}\)
(B) \(\left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{4}\right]^{2+}\)
c \(\mathrm{Cu}(\mathrm{OH})_{2}\)
D \(\mathrm{CuCO}_{3} \cdot \mathrm{Cu}(\mathrm{OH})_{2}\)

Answer 1

Solution:
\(\mathrm{NH}_{2} \mathrm{CONH}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow\)
\(\underset{(A)}{\left(\mathrm{NH}_{4}\right)_{2} \mathrm{CO}_{3}} \rightleftharpoons \underset{(B)}{2 \mathrm{NH}_{3}}+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2}\)
