Question

Which kind of chemical reaction takes place when electric current is passed through fused lead bromide

Answer 1

Assuming that the fused bromide is that of lead (II), at the cathode, the half-reaction is Pb+2 + 2e- -> Pb; at the anode, the half-reaction is 2 Br-1 -> Br2 + 2 e-. The total reaction is therefore PbBr2 -> Pb + Br2. Any of several names could apply to this reaction: "electrolysis"; "decomposition"; or "electrolytic decomposition" would usually be most likely to be used.

Answer 2

Answer:

Decomposition takes place
