$0.45 g$ of acid molecular weight 90 is neutralised by $20 ml$ of $0.5 N$ caustic potash. The basicity of acid is

Options:

Answer:

Solution:

Eq. of acid = Eq of base, $∴ \frac{0.45}{E \cdot wt} = \frac{20 \times 0.5}{1000} = E wt = 45 Basicity = \frac{M \cdot wt}{E \cdot wt} = \frac{90}{45} = 2$
