Question
The products formed when an aqueous solution of NaBr is electrolysed in a cell having electrodes are :
Options
A.Na and Br2
B.Na and O2
C.H2, Br2 and NaOH
D.H2 and O2
Solution
NaBr ⇋ Na+ + Br-
At cathode
Br- → Br + e-
Br + Br → Br2
So the products are H2 and NaOH (at cathide) and Br2 (at anode)
At cathodeBr- → Br + e-
Br + Br → Br2
So the products are H2 and NaOH (at cathide) and Br2 (at anode)
