Write the balanced net ionic equation for the precipitation of cobalt(II) sulfide from aqueous solution: Include states of matter in your answer.

Answer 1

The net ionic equation for formation of a precipitate is simply the aqueous forms of the ions making up the precipitate and the precipitate itself. So, the net ionic equation for formation of cobalt (II) sulfide (CoS) is...

Co²⁺(aq) + S^2-(aq) ==> CoS(s)
