Question

When do you use methyl orange in titration, when do you use phenolphathalein in titration?

Answer 1

Use phenolphthalein when titrating a weak acid against a strong base.

Use methyl orange when titrating a strong acid with a weak base.

Either can be used if both acid and base are strong.
