Consider the following equations : 2 Fe 2 + + H 2 O 2 → xA + yB (in basic medium) 2 MnO 4 - + 6 H + + 5 H 2 O 2 → x ' C + y ' D + z ' E (in acidic medium) The sum of the stoichiometric coefficients x , y , x ' , y ' and z ' for products A , B , C , D and E respectively, is _______

Correct answer

0

Step-by-step solution

(i)   2 Fe 2 + + H 2 O 2 → 2 Fe 3 + + 2 OH − ( ii )     2 MnO 4 - + 5 H 2 O 2 + 6 H + ⟶ 2 Mn 2 + + 5 O 2 + 8 H 2 O So sum of x + y + x 1 + y 1 + z 1 = 2 + 2 + 2 + 5 + 8 = 19
