To balance chlorine and potassium, 14 molecules of HCl are required. K … WebAnswer (1 of 6): This is a redox reaction. At least some of the chloride ions of HCl get oxidized to Cl2, so nominally each of those Cl^- ion loses an electron. Each of the two chromium atoms in Cr2O7^2- ion nominally gains 3 electrons and gets reduced to Cr^+3 monatomic ion. So, to balance elect...
