Question

write any two functions of Salt bridge​

Answer 1

Answer:

⟶ a commonly used form of salt bridge consists of a glass u- tube containing semi- solid paste of either kcl, kno_3kno

3

or nh_4clnh

4

cl in gelatin or agar-agar jelly.

\long right arrow⟶ the electrolytes that are often used in salt bridge are called inert electrolytes which are supposed:

not to interact chemically weather of the solutions present in a anodic or cathodic chambers.

not to interfere with overall cell reaction.

only those electrolytes can be used in a salt bridge in which mobility of ions is almost the same.

example, kcl, < strong > k_2so_4 < /strong ><strong>k

2

so

4

strong , etc.

long right arrow⟶ a salt bridge carries out two important functions:

it allows only flow of ions through it. thus, the circuit is completed.

it also maintains the electrical neutrality.

hope it helps to you dear
