MCQ
The indicator used in the titration of sodium carbonate with sulphuric acid is
- APhenolphthalein
- ✓Methyl orange
- CPotassium ferrocynide
- DPotassium ferricynide
✓
Answer
Correct option: B.
Methyl orange
b
The indicator used in the titration of sodium carbonate with sulphuric acid is Methyl orange Because it changes colour at the $pH$ of a mid-strength acid, it is usually used in titration for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but it has a sharp end point.
