Question

The titration shown here has the equivalence point at ph=3.2 which indicators will be appropriate to use

Answer 1

Answer:

Methyl orange.

Explanation:

• Every indicator has a pH working range.

• Methyl orange has the pH range (3-5).

• Chemists use methyl orange as an indicator in the titration of weak bases with strong acids.

• It changes from red (at pH 3.1) to orange-yellow (at pH 4.4) to yellow (at pH > 4.4).
