A solution is made that is 1.2×10−3 M in Zn(NO3)2 and 0.130 M in NH3. After the solution reaches equilibrium, what concentration of Zn2+(aq) remains?

Explanation:

Equation for the reaction can be expressed as:

    ⇄    

From the equation above; we use the ICE table to determine how much complex ion forms  in order to be able to calculate  the at equilibrium.

So;

                                     ⇄    

Initial                                                    

Change                          

Equilibrium                                                    

  ⇒  

=  

=  

=

Therefore, the concentration of Zn2+(aq) after the solution reaches equilibrium =
