Question

Which ions, if any, are spectator ions in the reaction agno3(aq)+nacl(aq)→agcl(s)+nano3(aq)? express your answers as ion separated by a comma?

Answer 1

Ag⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + Cl⁻(aq) → AgCl(s) + NO₃⁻(aq) + Na⁺(aq)

NO₃⁻, Na⁺

Answer 2

Answer : The spectator ions are,
`Na^+,NO_3^-`

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

`AgNO_3(aq)+NaCl(aq)\rightarrow NaNO_3(aq)+AgCl(s)`

The ionic equation in separated aqueous solution will be,

`Ag^+(aq)+NO_3^(-)(aq)+Na^(+)(aq)+Cl^(-)(aq)\rightarrow AgCl(s)+Na^+(aq)+NO_3^(-)(aq)`

In this equation,
`Na^+\text{ and }NO_3^-` are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

`Ag^(+)(aq)+Cl^(-)(aq)\rightarrow AgCl(s)`

Hence, the spectator ions are,
`Na^+,NO_3^-`
