Textbook Question
Chapter 17, Problem 79E
Methyl red has a pKaof 5.0 and is red in its acid form and yellow in its basic form. If several drops of this indicator are placed in 25.0-mL sample of 0.100 M HCI, what color does the solution appear? It 0.100 M NaOH is slowly added to the HCI sample, in what pH range will the indicator change color?
