The addition of sodium hydroxide will cause the chromate ions to react with the hydroxide ions to form a brown precipitate of chromium(III) hydroxide. This will result in a decrease in the concentration of chromate ions in the solution, shifting the equilibrium to the left. The solution will appear to become less orange and more yellow as the chromate ions are consumed in the formation of the precipitate.
