Statement 1: When 20 ml of 0.2 M - solution is titrated with 0.1 M - solution using phenolphthalein indicator, 20 ml of acid solution is consumed at the end point.
Statement 2: With phenolphthalein indicator, is neutralized only up to the stage.
Options:
Answer:
D
Solution:
20 ml 0.2 M = 4 mmol . With phenolphthalein, neutralization stops at (1 eq per mol), so 4 mmol = 40 ml of 0.1 M, not 20 ml - I is incorrect. II is correct: the phenolphthalein end point corresponds to conversion of into only. Hence (d).
