Question
Write balanced equation for the following conversion :
$CuSO _4 \xrightarrow{ A } Cu ( OH )_2 \xrightarrow{ B }\left[ Cu \left( NH _3\right)_4\right] SO _4$
✓

Answer

$CuSO _4 \xrightarrow{2 NH _4 OH } Cu ( OH )_2+\left( NH _4\right)_2 SO _4$
$Cu ( OH )_2+\left( NH _4\right)_2 SO _4+2 NH _4 OH \longrightarrow\left[ Cu \left( NH _3\right)_4\right] SO _4+4 H _2 O $
