Question

using Le Chanteliers principle what will happen and why when NaOH is introduced into iron(III) thicyanate ion equilibrium system

Answer 1

• More [FeSCN]²⁺ will be consumed shifting the reaction to the left.

Step-by-step explanation:

Th equilibrium equation for iron(III) thiocyanate ion is:

Fe³⁺ + SCN⁻ ⇄ [FeSCN]²⁺

When NaOH is introduced into the equilibrium system, part of the OH⁻ ions react with the Fe³⁺ ions in solution, as per the chemical equation:

Fe³⁺ + 3OH⁻ ⇄ Fe(OH)₃ ↓ (solid precipitate)

Threfore, the concentration of Fe³⁺ ions in solution decreases.
