Question
In the titration of 
, the indicator used is
- Methyl orange
- Methylene blue
- Phenolphthalein
- Litmus
The correct answer is: Methyl orange
pH of the solution at the equivalence point is on the acidic side due to dissolution of 
formed. A slight excess of strong acid lowers pH to 3.5 when methyl orange produces red colour.
