The indicator methyl red has a pKHIn=4.95. It changes from red to yellow over the pH range from 4.4 to 6.2.

Part A I

f the indicator is placed in a buffer solution of pH = 4.60, what percent of the indicator will be present in the acid form, HIn, and what percent will be present in the base or anion form, In−? Express your answer using two significant figures. Enter your answers numerically separated by a comma.
