CuSO4 + CoCl2 = CoSO4 + CuCl2 is a Double Displacement (Metathesis) reaction where one mole of aqueous Cupric Sulfate [CuSO4] and one mole of aqueous Cobaltous Chloride [CoCl2] react to form one mole of aqueous Cobalt(II) Sulfate [CoSO4] and one mole of aqueous Cupric Chloride [CuCl2]...
CuSO4 与 Pb(NO3)2 反应为：CuSO4 + Pb(NO3)2 = PbSO4↓ + Cu(NO3)2 ，形成白色沉淀。但 CuSO4 与 CaCl2 ：CuSO4 + CaCl2 不产生明显变化。CuSO4 跟 Hg(NO3)2 作用：CuSO4 + Hg(NO3)2 = HgSO4↓ + Cu(NO3)2 ，有沉淀出现。CuSO4 与 CoCl2 相遇：CuSO4 + CoCl2 不发生反应。然而 CuSO4 和 ...
