In base vs. Acid titration, at the end point methyl orange is present as
  1. quinonoid form
  2. heterocyclic form
  3. phenolic form

Solution

Methyl orange is a popular pH indicator that is used in the acid base titration.Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point.The colour of the solution changes from yellow to red when methyl orange is used as an indicator.That means in acidic medium it is red and exists in quinonoid form
