Half ionic equations
WebElectrolysis of aqueous sodium chloride. In the electrolysis of aqueous sodium chloride the half equation at the negative electrode (cathode) is: 2H+ + 2e– H2 Reduction. At the positive electrode (anode) chlorine gas is produced by the discharge of chloride ions: 2Cl– – 2e– Cl2 Oxidation. or. 2Cl– Cl2 + 2e–. WebThis ionic equation can be split into two half equations: Mg (s) → Mg2+(aq) + 2e- (oxidation) 2HCl+(aq) + 2e- → HCl2(g) (reduction) Notice that: magnesium atoms lose electrons - they are...
