Question
When a strong base is added to a solution of CuSO4, which is pale blue, a precipitate forms and the
solution above the precipitate is colorless. What is the net chemical equation that describes this reaction?
Include the phases of all species in the chemical equation.
When ammonia is then added, the precipitate dissolves and the solution turns a deep navy blue. What is the
net chemical equation that describes this event? Include the phases of all species in the chemical equation.
Cu(OH)₂(s) + 4NH₂(aq) → [Cu(NH₂)]²+ (aq) + 2OH¯(aq)
Tip: Plus signs (+) can be typed from the keyboard. Reaction arrows can be found in the Tools
menu of the answer module. Include phases in the balanced chemical equation. Click on the
(aq) button in the tools to select the phase to add. Phases should not be subscripted.
