Webhalf-equation 1: Cu (s) Cu 2+ (aq) + 2e. half-equation 2: Ag + (aq) + 1e Ag (s) It should be seen that if we simply add these equations together there will be one extra electron remaining on the right hand side. Before the equations can be added, the second equation must be multiplied through by 2 to give: WebNet ionic equation: 6 C l X 2 ( g) + 6 H X 2 O ( l) 8 C l X − ( a q) + 4 C l O X 3 X − ( a q) + 12 H X + The answer to this problem is however given as 2 C l X 2 ( g) + 6 H X 2 O ( l) 2 … WebOxidation of ClO (-) into ClO3 (-) 0.25ClO (-) + 0.5 H2O --> 0.25ClO3 (-) + H (+) + e (-) Now add the two equations, and everything simplifies nicely with the hydrogen ions, electrons and waters cancelling out. 0.75 ClO (-) --> 0.5 Cl (-) + 0.25 ClO3 (-) This can also be written with integer coefficients of 3, 2 and 1 respectively. orange banner aesthetic
