Addition of Fe(NO3)3(aq) from the equilibrium mixture.

Addition of Mg(OH)2(s) to the equilibrium mixture.

Addition of Mg(NO3)2(s) to the equilibrium mixture.

A.

Addition of HCl(aq) to the equilibrium mixture.

B.

Addition of NaOH(s) to the equilibrium mixture.

C.

Addition of Fe(NO3)3(aq) from the equilibrium mixture.

D.

Addition of Mg(OH)2(s) to the equilibrium mixture.

E.

Addition of Mg(NO3)2(s) to the equilibrium mixture.

Explanation / Answer

Answer: C

Addition of HCl(aq) to the equilibrium mixture
This will react with OH- and shift the equilibrium towards right

Addition of NaOH(s) to the equilibrium mixture.
This will provide OH- and shifts the equilibrium towards left due to common ion  

Addition of Mg(OH)2(s) to the equilibrium mixture.
This will shifts the equilibrium towards right

Addition of Mg(NO3)2(s) to the equilibrium mixture.
This will provide Mg2+ and shifts the equilibrium towards left due to common ion
