Question

when fused lead bromide Is electrolysed what we observe?​

Answer 1

$\huge\bf\underline\mathfrak\red{Answer :}$

When the fused lead bromide is electrolysed, the formation of silver - coloured substance ( also referred as silver-grey ) at the cathode along with the emission of reddish-brown gases ( also called fumes ) at anode is observed.

1. Electrolysis is the process in which, with the application of electricity, several electrolytes are splitted to produce elements.
2. During the electrolysis of fused lead bromide, the movement of negative ions ( also called anions ) to anode is observed.
3. The room temperature is not enough for meeting the requirements of lead bromide in order to conduct the electricity, the temperature must be around 370°C.
4. For this reason, molten lead bromide is chosen for the process of electrolysis.

Answer 2

Answer:

hii

answer toh pata nhi but i hope its help you...

Explanation:

When fused lead bromide is electrolyzed we observe a silvery grey deposit at cathode and reddish brown fumes at anode.
