Copper nitrate reacts with potassium iodide to form copper iodide and potassium nitrate. The chemical formulas for copper nitrate and potassium iodide are Cu(NO3)2 and KI respectively. The ionic equations for the reaction are;
Cu(NO3)2 ------ > Cu+2 + 2NO3-1
KI ------ > K+1 + I-1
Cu+2 + 2I-1 ------ > CuI2
K+1 + NO3-1 ------ > KNO3
K+1 + NO3-1 + Cu+2 + 2I-1 ------ > KNO3 + CuI2
The balanced equation for the reaction is;
Cu(NO3)2 + 2KI ------ > 2KNO3 + CuI2
Cu(NO3)2 ------ > Cu+2 + 2NO3-1
KI ------ > K+1 + I-1
Cu+2 + 2I-1 ------ > CuI2
K+1 + NO3-1 ------ > KNO3
K+1 + NO3-1 + Cu+2 + 2I-1 ------ > KNO3 + CuI2
The balanced equation for the reaction is;
Cu(NO3)2 + 2KI ------ > 2KNO3 + CuI2
