At anode fe 2+→fe 3++e −. Cr 2o 72−+6fe 2++14h +→2cr 3++fe 3++7h 2o. Cr 2o 72− undergo reduction at cathode while fe 2+ converted to fe 3+ (oxidation ) occur at anode this is redox reaction.
The limiting reagent row will be highlighted in pink. Examples of complete chemical equations to balance: Fe + cl 2 = fecl 3.
Kmno 4 + hcl = kcl + mncl 2 + h 2 o + cl 2. K 4 fe (cn) 6 + h 2 so 4 + h 2 o = k 2 so 4 + feso 4 + (nh 4) 2 so 4 + co. C 6 h 5 cooh + o 2 = co 2 + h 2 o.
