balance the following reaction by oxidation number method I2 + S2O3 -----> I- + S4O6 2- (neutral) Share with your friends Share 1 Geetha answered this The given skeleton equation isI2 + S2O32- →I- + S4O62- (you missed the LHS charge)The oxidation state of I and SLHSI22x=0x=0RHSI-x= -1S2O32x + 3(-2) =-22x= 4x= +2S4O62-4x+2(-2) + 4(-1)=-24x= 10x= 2.5Thus the oxidation state changes are I changed from 0 to -1 and S changed from2 to 2.5I2 + S2O32- →I- + S4O62-2 1 (oxidation number changes calculated for total number of atoms of I and S)Cross multiplyI2 + 2S2O32- →I- + S4O62-Balance the right sideI2 + 2S2O32- →2I- + S4O62-Thus its a balanced equation. 2 View Full Answer Sam answered this cant! 0
