Question

Give five examples of redox reactions.

Answer 1

a). 2KMNO4 + 10FeSO4 + H2SO4 = 2MnO +K2SO4 + H2O + 5Fe2(SO4)3

b). K2Cr2O7 + 6FeSO4 + 7H2SO4 = Cr2(SO4)3 + 3Fe2(SO4)3 + 7H2O + K2SO4

CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4
2Fe3+ + Sn2+ -> 2Fe2+ + Sn4+
Fe (metal) + Cu2+ -> Fe2+ + Cu (metal)
Zn + 2HCl -> Zn2+ + H2 +2Cl-
3CuS + 8HNO3 -> 3 CuSO4 + 8NO(g) + 4H2O
or if u want easy
1. Cellular respiration

2. The formation of rust or corrosion of iron.

3. Zinc metal place in hydrochloric acid for the formation of hydrogen gas.

4. A combustion reaction involving the burning of gasoline in oxygen.

5. Zinc and manganese dioxide in a battery react to produce electricity
