Question

the following equilibrium reaction occurs in aqueous solutions when 0.1 M KSCN is mixed with 0.1 M

Fe(NO3)3. Fe(SCN)2+(aq) <----> Fe3+(aq) + SCN-(aq)

Predict whether the following statements (in relation to the above equilibrium reaction in aqueous solution) are "True" or "False".

1.Addition of 0.1 M NaNO3 does not have as much influence on the position of the equilibrium.

2.Addition of 0.1 M KSCN does not affect the position of the equilibrium.

3.Addition of 0.1 M KNO3 causes the equilibrium to shift to the left (reactant side).

4.Addition of 0.1 M Fe(NO3)3 causes the equilibrium to shift to the right (product side).

5.In the addition of 6 M NaOH, OH- reacts with Fe3+ to form slightly soluble Fe(OH)3.

6.Addition of 0.1 M LiSCN will have a similar effect on the position of the equilibrium as the addition of 0.1 M KSCN.

7.Addition of 6 M NaOH causes the equilibrium to shift to the left because NaOH is a strong base and breaks the bonds in Fe(SCN)2+
