Orange Tornado

The video tutorial demonstrates a precipitation reaction using mercury chloride and potassium iodide solutions. It explains the setup and observation of the reaction, where an orange precipitate forms and vanishes. The chemical process involves the dissociation of salts into ions, leading to the formation of mercury iodide and a secondary reaction producing potassium Tetraioda mercurate. The tutorial also highlights the application of precipitation reactions in water treatment to remove toxic ions.

Explain the significance of the vortex created by the magnetic stirrer in the experiment.

How do oppositely charged ions behave in a solution?

What role do water treatment plants play in removing toxic ions from solutions?
