Sodium carbonate, also called soda ash, is often analyzed by titration with strong acid. Initial concentrations of the carbonate ions are about 0.1 M. What indicator(s) would be suitable for detecting the stoichiometric point in this titration? (for H2CO3: pKa1 = 3.75 pKa2 = 10.33) Indicator Color at pH’s I. methyl orange 2.8 (red) - 3.5 (yellow) II. methyl red 4.4 (red) - 6.2 (yellow) III. phenol red 6.4 (yellow) - 8.0 (red) IV. thymol blue 8.0 (yellow) - 9.6...
