ChemistryMediumassertion reason
Assertion : In the titration of with HCl using methyl orange indicator, the volume of the acid required at the equivalence point is twice that of the acid required using phenolphthalein as indicator.
Reason : Two moles of HCl are required for the complete neutralization of one mole of Na2CO3.
Options:
Answer:
B
Solution:
Na₂CO₃ needs 2HCl → complete neutralisation
So methyl orange volume = 2 × phenolphthalein
Both true but Reason not full explanation
