An equilibrium reaction between chromate ions, CrO4 2- (yellow), and H+ ions is established to produce dichromate, Cr₂072- (orange). Note the colours. A student adds NaOH to a test tube containing an orange mixture of the above reagents. What is observed? O 1. The solution turns from orange to yellow O 2.A precipitate forms 3. The solution tuirns from orange to colourless O 4. The solution remains orange
