What will be the titre reading if methyl orange is added after the first end point with phenolphthalein?
Options:
Answer:
A
Solution:
After the phenolphthalein end point the solution contains from (4.72 mmol) plus the original (5.95 mmol). Methyl orange then neutralizes these to : 4.72 + 5.95 = 10.67 mmol . Titre = 10.7 ml, matching (a).
