I completely understand Le Chateliers principle but I have no idea about these questions. They're due tomorrow so fast help would be appreciated.

Why did adding water to the equilibrium involving CoCl_4_^2-^ cause the color to change?

Use Le Chateliers principle to explain the different colors found in the following equilibria. Show all chemical reactions.
My results were that it turned orange before HCl, yellow after NaOH, and pink after HCl.

How does Le Chateliers principle explain the result you obtained when you added HCl to a suspension of Ca(OH)_2_ in water?

How does Le Chateliers principle explain the result you obtained after the addition of NaOH?

Thank you!
