    Which will make basic buffer?                                                                                           [NEET 2019]

    A)  \[100\text{ }mL\text{ }of\text{ }0.1\text{ }M\text{ }HCl+200\text{ }mL\text{ }of\text{ }\]\[0.1M\text{ }N{{H}_{4}}OH\]

    B) \[100\text{ }mL\text{ }of\text{ }0.1\text{ }M\text{ }HCl+100\text{ }mL\text{ }of\text{ }\]\[0.1\text{ }M\text{ }NHOH\]

    C)  \[50\text{ }mL\text{ }of\text{ }0.1\text{ }M\text{ }NaOH+25\text{ }mL\text{ }of\]\[0.1\text{ }M\text{ }C{{H}_{3}}COOH\]

    D)  \[100\text{ }mL\text{ }of\text{ }0.1\text{ }M\text{ }C{{H}_{3}}COOH+100\]\[mL\text{ }of\text{ }0.1\text{ }M\text{ }NaOH\]

    Correct Answer: A

    Solution :

    [a] Weak Acid > Strong Base
    Weak Base > Strong Acid
    \[M\text{ }200\text{ }Ml\text{ }N{{H}_{4}}OH>0.1\text{ }M\text{ }100\text{ }Ml\text{ }HCl\]
