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

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.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the answer is 0.42 is that is an option. this question provides no info
