What happens when I mix KSCN with FeCl3? What happens when I add NaOH to FeCl3?
For both of the reactions (KSCN and Fecl3 ; NaOH and FeCl3) I got no color change whatsoever. I have a feeling that I did something wrong, so can somebody explain to me whether this was supposed to happen or not?
A color change is what is supposed to happen. The first reaction KSCN + FeCl3, is used for moderately realistic "blood" effects in the film and theater industry. Dilute aqueous potassium thiocyanate (KSCN) can be painted on a surface or kept as a colorless solution. When in contact with ferric chloride solution (or any other solution offering Fe +3), the production of the reaction is a solution with a blood red color. This is due to the formation of the thiocyanatorium ion.
The ferric chloride (FeCl3) is another color indicator of phenols and enols. It can range in color from red. orange, green, and purple. My guess is you mixed the wrong reactants, or something contaminated the reaction. Try again!
