Concentration change - Potassium ferricyanide experiment

The video tutorial explains the formation of potassium ferrous cyanide through an experiment involving potassium thiocyanide and ferric nitrate. The reaction results in a color change from pale yellow to deep red due to the formation of potassium ferric thiocyanide. The process is an equilibrium reaction, and the video details how removing ferric ions or adding thiocyanide ions affects the equilibrium, causing color changes. The tutorial also covers the restoration of equilibrium and the chemical reactions involved.

What is the result of the backward reaction when the ferric ion is restored?

Describe the process that occurs when the concentration of thiocyanide ion increases in the solution.
