Choose the correct answer from the options given below:
When fused lead bromide is electrolyzed we observe:
a silver-grey deposit at cathode and reddish brown fumes at anode
Explanation for the correct option:
(c)a silver-grey deposit at cathode and reddish-brown fumes at anode
During the electrolysis of fused Lead Bromide, the silver-grey-colored substance is deposited at the cathode and reddish-brown fumes come out from the anode.
Explanation for the incorrect option:
(a) a silver-grey deposit at anode and a reddish-brown deposit at cathode
During the electrolysis, a silver-grey-colored substance gets deposited at the cathode. So this is the incorrect option.
(b) a silver-grey deposit at cathode and a reddish-brown deposit at anode
During the electrolysis, reddish-brown fumes comes out from the anode. So this is the incorrect option.
(d) silver grey fumes at the anode and reddish-brown fumes at the cathode
A silver-grey substance gets deposited during the process of electrolysis. So, this is the incorrect option.
When fused lead bromide is electrolyzed we observe a silver-grey deposit at the cathode and reddish-brown fumes at the anode.
