Описание: Yellow chromate and orange dichromate are in equilibrium with each other in aqueous solution. The more acidic the solution, the more the equilibrium is shifted to the right towards the dichromate ion. As nitric acid is added to the chromate solution, the yellow color turns to orange. When sodium hydroxide is added to the chromate solution, the orange color turns back to yellow. The sodium hydroxide reacts with hydrogen ions, removing them from the solution. When one reactant is removed from an equilibrium system, the equilibrium shifts from the right back toward the left, in this case forming yellow chromate ion again.
