which of the following is an accurate net ionic equation representing the cross reaction between KOH and CuSO4 solutions? Select all that apply. Because no insoluble precipitate can form, there is no reaction. CuSO4(aq) + KOH(aq) -> CuOH(s) + KSO4(aq) CuSO4(aq) + 2KOH(aq) -> Cu(OH)2(s) + K2SO4(aq) Cu2+(aq) + OH–(aq) -> CuOH(s) Cu2+(aq) + 2OH–(aq) -> Cu(OH)2(s) 2K+(aq) + SO42-(aq) -> K2SO4(s)
