Suppose you have an indicator that is diprotic and has pKa1 = 3 and pKa2 = 7. If H2In is yellow, HIn- is red, and In2- is blue, what species is/are significantly present at pH of 7? what is the color of the indicator at a pH of 7?

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
