Name two gases other than sulphur dioxide and hydrogen sulphide which are reducing agents.
Carbon monoxide (CO) and Ammonia (NH3) gas act as reducing agents.
Two gases found dissolved in natural water are
(a) oxygen and carbon dioxide
(b) hydrogen and oxygen
(c) sulphur dioxide and hydrogen
(d) chlorine and ammonia
When the gases sulphur dioxide and hydrogen sulphide mix in the presence of water the reaction is :
SO2+2H2S=2H2O+3S
Here hydrogen sulphide is acting as :
A. Oxidizing agent
B. Reducing agent
When the gases sulphur dioxide and hydrogen sulphide mix in the presence of water, the reaction is . Here, the hydrogen sulphide is acting as
