The photograph below shows what occurs when a solution of potassium chromate is treated with a few drops of concentrated hydrochloric acid. Some of the bright yellow chromate ion is converted to the orange dichromate ion. 2 CrO 4 2− (aq) + 2 H 3 O + (aq) ⇄ CrO 7 2− (aq) + 3 H 2 O( ℓ ) (a) Explain this experimental observation in terms of Le Chatelier’s principle. (b) What would you observe if you treated the orange solution with sodium hydroxide? Explain your observation.
