What happens upon the addition of NaOH solution (OH- ions) to a pink solution of cobalt chloride? Include equation(s) in your answer.

A blue precipitate is formed when both a few drops, or excess, of NaOH is added to a solution of cobalt chloride; this is an example of an acid-base chemical reaction.The relevant equation is: [Co(H2O)6]2+(aq) + 2OH-(aq) >>> Co(H2O)4(OH)2 (s) + 2(H2O) (l).
