Question

Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed.

Answer 1

`2Li^+_((aq))+S^(2-)_((aq))+Cu^(2+)_((aq))+2NO_3^(-)_((aq))\rightarrow CuS_((s))+2Li^+_((aq))+2NO_3^(-)_((aq))`

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.

The balanced molecular equation will be,

`Li_2S_((aq))+Cu(NO_3)_2_((aq))\rightarrow CuS_((s))+2LiNO_3_((aq))`

The complete ionic equation in separated aqueous solution will be,

`2Li^+_((aq))+S^(2-)_((aq))+Cu^(2+)_((aq))+2NO_3^(-)_((aq))\rightarrow CuS_((s))+2Li^+_((aq))+2NO_3^(-)_((aq))`
