The net ionic equation for the reaction of Fe3+ and NaF is
The iron(iii) fluoride complex is more stable compared to the iron(iii) thiocyanate complex.
A net ionic equation is an equation where only the ions reacting to form a product is shown in the equation.
The net ionic equation of the reaction of the Fe3+ ion and sodium fluoride is shown below:
When sodium fluoride is added to a solution of iron (iii) thiocyanate (red), the red colour disappears because the flouride ions displace the thiocyanate ions.
This is because the iron(iii) fluoride complex is more stable compared to the iron(iii) thiocyanate complex.
