Why Is Iron Thiocyanate Red?

Why Is Iron Thiocyanate Red? The FeSCN2 + complex that is formed as a result of reaction between iron(III) and thiocyanate ions has a very intense blood red color (or orange in dilute solution), allowing for easy detection and quantitative determination by spectrophotometry. Reactants ( Fe3 + and SCN-) are practically colorless. What is the

Is The Reaction Between Iron And Thiocyanate Exothermic?

Is The Reaction Between Iron And Thiocyanate Exothermic? When the iron ion concentration was increased, the red color reappeared and the solution became cloudy. Increasing the thiocyanate ion concentration had no effect. … This equilibrium shift to the left suggests that the reaction is exothermic, and that heat is generated when the iron thiocyanate product
