A) \[0.1M\,C{{H}_{3}}COOH\]
B) \[0.1\text{ }M\text{ }HN{{O}_{3}}\]
C) \[0.05M\,{{H}_{2}}S{{O}_{4}}\]
D) \[50\text{ }c{{m}^{3}}\,0.4\text{ }M\,HCl+50\text{ }c{{m}^{3}}\text{ }0.2\text{ }M\text{ }NaOH\]
Correct Answer: A
Solution :
\[0.1\text{ }M\text{ }C{{H}_{3}}COOH\] is not completely dissociated. Therefore, pH will not be one.
