Question

The following molecular equation represents the reaction that occurs when aqueous solutions of silver(I) nitrate and chromium(III) bromide are combined. 3AgNO3 (aq) + CrBr3 (aq) --> 3AgBr (s) + Cr(NO3)3 (aq) Write the balanced net ionic equation for the reaction.

Answer 1

The balanced net ionic equation for the reaction between silver(I) nitrate and chromium(III) bromide is 3Ag+ (aq) + 3Br- (aq) --> 3AgBr (s).

Step-by-step explanation:

The balanced net ionic equation for the reaction between aqueous solutions of silver(I) nitrate and chromium(III) bromide is:

3Ag+ (aq) + 3Br- (aq) --> 3AgBr (s)

In this reaction, the silver ions (Ag+) combine with the bromide ions (Br-) to form solid silver bromide (AgBr). The chromium(III) ions (Cr3+) and the nitrate ions (NO3-) do not participate in the reaction and are therefore considered spectator ions.

Answer 2

`3Ag^+_((aq))+3Br^(-)_((aq))\rightarrow 3AgBr_((s))`

Step-by-step explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

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

Only the species which are present in aqueous state dissociate.

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 balanced molecular equation will be,

`3AgNO_3_((aq))+CrBr_3_((aq))\rightarrow 3AgBr_((s))+Cr(NO_3)_3_((aq))`

The complete ionic equation in separated aqueous solution will be,

`3Ag^+_((aq))+3NO_3^-_((aq))+Cr^(3+)_((aq))+3Br^(-)_((aq))\rightarrow 3AgBr_((s))+3NO_3^-_((aq))+Cr^(3+)_((aq))`

In this equation the species present are,
`Cr^(3+)\text{ and }3NO_3^-` are the spectator ions.

Hence, the net ionic equation contains specie is

`3Ag^+_((aq))+3Br^(-)_((aq))\rightarrow 3AgBr_((s))`
