Question

What is the net ionic for
CoCo3+2HNO3-->Co(NO3)2+CO2 +H2O

Answer 1

break them into ions first

Answer 2

To write a net ionic equation, you must determine the state of matter of each compound or molecule. If it is a solid, liquid or gas it will form a precipitate and not break apart into ions. If a compound or molecule is in an aqueous state, it will break apart into ions.

There are rules to follow to determine if a compound will be soluble or not. Note that all soluble compounds will dissolve in water and insoluble compounds will not (form a precipitate).


CoCo3(s) + 2HNO3(aq) -> Co(NO3)2(aq) + CO2(g) + H2O(l)

So after separating the aqueous and gaseous compounds into ions, we get:

CoCo3 + 2H+1 + 2(NO3)-1 -> Co+2 + 2(NO3)-1 + CO2 + H2O


Get rid of the spectator ions (the ions on both sides of the equation) and we get the net ionic equation.

CoCo3 + 2H+1 -> Co+2 + CO2 + H2O
