A) cupra ammonium sulphate
B) cupra ammonium hydroxide
C) sodium hexametaphosphate
D) ammonal
Correct Answer: A
Solution :
\[CuS{{O}_{4}}(aq)+2N{{H}_{4}}OH\xrightarrow{{}}\underset{Cupric\,hydroxide}{\mathop{Cu(OH)\downarrow }}\,\]\[+{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\] \[\underset{\begin{smallmatrix} Cupric \\ hydroxide \end{smallmatrix}}{\mathop{Cu{{(OH)}_{2}}(s)}}\,+2N{{H}_{4}}OH+{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\xrightarrow{{}}\] \[\underset{\begin{smallmatrix} Intense\,blue\,colour \\ cupra\,ammonium\,sulphate \end{smallmatrix}}{\mathop{[Cu{{(N{{H}_{3}})}_{4}}]S{{O}_{4}}(aq)+4{{H}_{2}}O}}\,\]You need to login to perform this action.
