Question

(i) What are redox reactions? Identify the substances that are oxidised and the
substances that are reduced in the following reactions :
(a) 2H,SE) + SO2(g) 3S) + 2H,0a)
(b) Cuos) + H28) _Cus) +H,0a)
(c) MnO, + 4HC1 — MnCl2 + 2H,0 + C1,1​

Answer 1

Answer:

there is oxidation and reduction both take place is called redox reaction

Answer 2

Answer:

those reactions in which oxidation and reduction occur simultaneously

substances oxidised substances reduced

H SO2

H2 CuO

H MnO
