Answer:

  1. it connects the two different half cells
  2. it contains an inert electrolyte
  3. this electrolyte helps in maintaining neutrality
  4. inert electrolyte is chosen in such a way that velocity of the electrolytes components should be same and thee should reach both the half cells at the same time

Explanation:

\huge\mathtt\red{Answer}

\longrightarrow A commonly used form of salt bridge consists of a glass U- tube containing semi- solid paste of either KCl, KNO_3 or NH_4Cl in gelatin or agar-agar jelly.

\longrightarrow 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, K_2SO_4, etc.

\longrightarrow 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.
