Question

写出下列反应的离子方程式h2so4+cu(oh)2 zn+agna3 al+cucl2 caco3+hcl na2co3

Answer 1

2H+ + Cu(OH)2 == Cu2+ + 2H2O

Zn + 2Ag+ == Zn2+ + 2Ag

2Al + 3Cu2+ == 2Al3+ + 3Cu

CaCO3 + 2H+ == Ca2+ + H2O + CO2↑

CO3^2- + 2H+ == H2O + CO2↑

H+ + OH- == H2O

CuO + 2H+ == Cu2+ + H2O

Ag + Cl- == AgCl↓

Mg2+ + SO4^2- + Ba2+ + 2OH- == Mg(OH)2↓ + BaSO4↓
