Question 1

Describe briefly the steps to balance redox equations in acidic medium.

Answer 1

1. Balance number of atoms of substance
2. Balance number of O atoms
3. Balance number of H atoms
4. Balance overall charges with e-
5. Multiply to balance number of e- lost and gained
6. Sum up equations

Question 2

Describe briefly the steps to balance redox equations in basic/neutral/aqueous medium.

Answer 2

1. Balance number of atoms of substance
2. Balance number of O atoms
3. Balance number of H atoms
4. Balance overall charges with e-
5. Multiply to balance number of e- lost and gained
6. Sum up equations
7. Neutralise H+ with equal OH- added to both sides to form H2O and excess OH-
