A) \[0.1\text{ }M\text{ }HN{{O}_{3}}\]
B) \[0.05\text{ }M\text{ }{{H}_{2}}S{{O}_{4}}\]
C) \[0.1\text{ }M\text{ }C{{H}_{3}}COOH\]
D) \[50\,\,c{{m}^{3}}\]of \[0.4\,\,M\]\[HCl+50\,\,c{{m}^{3}}\]of \[0.2\,M\,NaOH\]
Correct Answer: C
Solution :
Among the given, pH of \[0.1\,M\,C{{H}_{3}}COOH\] is not equal to one as \[C{{H}_{3}}COOH\] is a weak acid, thus does not ionise completely.
