        0.45 g of acid of molecular weight 90 was neutralised by 20 mL of 0.5 N Caustic potash. The basicity of the acid is

    A)  1                                            

    B)  2

    C)  3                                            

    D)  4

    Correct Answer: B

    Solution :

                    \[Eq\,mass=\frac{Weighty(g)}{Number\text{ }of\text{ }equivalent}\] \[=\frac{0.45}{20\times 0.5\times {{10}^{-3}}}=45\] Basicity of the acid\[=\frac{Mol.\text{ }mass}{Eq.\,mass}=\frac{90}{45}=2\]
