Question

What are the spectator ions in
\[LiCl(aq)+AgN{{O}_{3}}\to AgCl(s)+LiN{{O}_{3}}(aq)\] ?

Answer 1

Hint: The ions which are not going to participate in the chemical reaction and stay throughout the chemical reaction means before and after the chemical reaction also they are present and do not precipitate in the solution.

Complete answer:
- In the question it is asked to find the spectator ions in the given chemical reaction.
- The given chemical reaction is as follows.
\[LiCl(aq)+AgN{{O}_{3}}\to AgCl(s)+LiN{{O}_{3}}(aq)\]
- In the above chemical reaction one mole of lithium chloride is going to react with one mole of the silver nitrate and forms one mole of silver chloride and one mole of lithium nitrate.
- Now we have to find the spectator ions in the above chemical reaction.
- After reaction the silver chloride is going to be obtained from the lithium chloride and silver nitrate is not going to soluble in the solution.
- Means the formed silver chloride after the chemical reaction is going to precipitate and settles at the bottom of the beaker in the form of a white crud precipitate.
- Means the silver from silver nitrate and chlorine from lithium chloride are going to participate in the chemical reaction then the other two counter parts are lithium ion and nitrate ions are not participating in the chemical reaction.
- Therefore the lithium ion and nitrate ions are the spectator ions in the given chemical reaction.

Note:
Spectator ions after the chemical reaction also will be in solution in aqueous form and do not involve in the chemical reaction at any stage. The ions are not going to be involved in the chemical reaction then those are called spectator ions.
