OH Task 3. A new anthocyanin is discovered. It has 2 weak acid functional groups, giving rise to the following observations: . When pH = 1.1 and below, colour - blue When pH = 3.3, colour - green When pH = 5.5, colour = yellow HO When pH = 7.7, colour = orange When pH = 9.9 and above, colour = red HO OCH . OH SO OH HO OH (a) When pH = 3.3 and when pH = 7.7, [anthocyanin yellow form] = 0.60 M (0.60 x 10-6 M). Estimate [anthocyanin red form) at pH = 11.1 in 50 words. (b) Which is the stronger acid, the blue form or the yellow form? Explain in 50 words
