Question

NH4NO3 is used in salt bridge because​

Answer 1

Answer:

Because the ionic velocity of the ammonium ion$(NH_4^+)$ and the nitrate ion $(NO_3^-)$ are the same in saltbridze, sodium chloride (NaCl) is not used because the ionic velocity of the cation and anion in sodium chloride is different.

Explanation:

• By permitting anions to migrate towards anodic compartments and cations to go towards cathodic compartments, the salt bridge preserves electrical neutrality in two compartments.
• It's a gelatin-coated glass tube containing potassium chloride or ammonium nitrate.
