16. Write the balanced molecular equation, the ionic equation and the net ionic equation for the reaction that occurs when solutions of CuSO4 and NH4OH are mixed.
Molecular equation: (4 points)
Ionic equation: (4 points)
Net ionic equation: (3 points)
ans) copper sulphate reacts with NH4OH to form precipitate of Cu ( OH)2 WHICH redissolves in
excess of NH4OH forming a complex , tetramine copper sulphate.
CuSO4 + 2 NH4OH --------------- Cu(OH)2 + ( NH4)2 SO4
Cu( OH )2 + 2 ( NH4) 2 SO4 -------------------------- [ Cu ( NH3 )4 ]SO4 + 2 H2O + H2SO4
