Which of the following acts both s a reducing and an oxidizing agent?
H2
SO2
H2S
C
Explicaţie
SO2 = i.e
In H2SO2 act as oxidizing agent
H2S + SO2 → 3S + 2H2O
Whereas in water SO2 acts as reducing agents H2O + SO2 H2SO23
In H2SO2 act as oxidizing agent
H2S + SO2 → 3S + 2H2O
Whereas in water SO2 acts as reducing agents H2O + SO2 H2SO23
