Fe3+(aq) (yellow) + scn-(aq) (colorless) fescn2+(aq) (blood-red) chloride ions are colorless. potassium ions are also colorless. the above equilibrium can be created by mixing an iron (iii) chloride solution with a potassium thiocyanate solution. based on this information and the colors in the equilibrium above answer the first two questions. 1. what color would an fecl3 solution be? 2. what color would a kscn solution be? 3. what color do you get when you mix fecl3 and kscn as shown in the video for the control test tube?
