Question

2AgNO3The following chemical reaction takes place in aqueous solution: (aq)(aq)(s)(aq) Write the net ionic equation for this reaction.

Answer 1

`2Ag^+(aq)+CO_3^(2-)(aq)\rightarrow Ag_2CO_3(s)`

Step-by-step explanation:

Hello.

In this case, since the reaction is not given but a typical precipitation of silver from silver nitrate could be represented by its reaction with a soluble metallic sulfide or carbonate since silver carbonate and silver sulfide are insoluble, we can use for instance sodium carbonate to obtain:

`2AgNO_3(aq)+Na_2CO_3(aq)\rightarrow Ag_2CO_3(s)+2NaNO_3(aq)`

Thus, since, silver nitrate, sodium carbonate and sodium nitrate are fully ionized by silver carbonate remains solid, the complete ionic equation is:

`2Ag^+(aq)+2NO_3^-(aq)+2Na^+(aq)+CO_3^(2-)(aq)\rightarrow Ag_2CO_3(s)+2Na^+(aq)+2NO_3^-(aq)`

Then, since nitrate and sodium ions are the spectator ions since they are at both reactants and products, the net ionic equation turns out:

`2Ag^+(aq)+CO_3^(2-)(aq)\rightarrow Ag_2CO_3(s)`
