The oxalic acid is added in test tube and this reaction Fe_((aq))^(3+)

1.	The oxalic acid is added in test tube and this reaction Fe_((aq))^(3+) + SCN_((aq))^(-) hArr [Fe(SCN)]_((g))^(2+)equilibrium, steered and remain the solution than what will the change in colour of solution ?
Answer» Solution :The intensity of red colour of solution is DECREASE because the oxalate ion, `C_2O_4^(2-)`of oxalic acid is reacts with `Fe^(3+)` ion and decrease the concentration of `Fe^(3+)`. The reaction should be forward an red colour containing `[Fe(SCN)]_((AQ))^(2+)`is decrease, the red colour decreases.
