Net ionic equations
« on: October 10, 2004, 07:44:00 AM »
can some1 help me out with writing the net ionic equation for:
H2SO4(aq) + Cu(OH)2 --> 2H2O(l) + CuSO4(s)
(by the way, is that CuSO4 meant to be solid or aqueous?)

I dont think solid copper(II) sulphate will be formed as it's water-soluble.

it should be
H2SO4 (aq) + Cu(OH)2 (s) --> CuSO4 (aq) + 2H2O (l)

First, we must elimiate the common ions present on the left and right hand side, which is sulphate only. Hence the ionic equation is:

2H+(aq) + Cu(OH)2(s) -> Cu2+(aq) + 2H2O(l)

then is CuSO4 also aqueous in this equation?
H2SO4(aq) + CuCO3(aq) --> CuSO4(?) + CO2(g) + H2O(l)

Yes, unless water is present in minute amount.
