To indicate the pH of a substance, one can use a dye that is both an acid and that appears as different colors in its protonated and deprotonated forms. Suppose that you have a 0.001 M solution of a dye with a pKa of 7.2. From the color, the concentration of the protonated form, HA, is 0.0002 M.. Assume that the remainder of the dye is in the deprotonated form, .A−.
What is the pH of the solution? Give your answer to one decimal place

Can you please check my work? I am having difficulty in
differentiating my answers from pH>pKa to pH<pKa. I do not
understand how acids and bases would be different among each other
in relation to pH and pKa. Guidance would be greatly appreciated.
Thank you.
