What would be the best indicator for the titration of 0.20 M CH3COOH titrated with 0.2 M NaOH? (Ka for acetic acid = 1.8 X 10-5) The pH ranges for the color change of some common acid base indicators are given below
Methyl Violet ; pH range 0-2
Methyl Red ; pH range 4-6
Alizarin yellow ; pH range 10-12
phenolphthalein; pH range 8-10
None of the above
