The neutralization occurs when 10 mL of 0.1M acid 'A' is allowed to react with 30 mL of 0.05 M base M(OH)2. The basicity of the acid 'A' is __________.
[M is a metal]
Answer (integer)
3
Solution
Milieq of acid $A=$ Milieq of base $M(O H)_{2}$
<br/><br/>
$$
\begin{aligned}
& \left(\mathrm{M} \times \mathrm{V} \times \mathrm{n}-\text { Factor }_{A}\right.=(\mathrm{M} \times \mathrm{V} \times \mathrm{n}-\text { Factor })_{\mathrm{M}(\mathrm{OH})_{2}} \\\\
& \left[\mathrm{n}-\text { Factor of } \mathrm{M}(\mathrm{OH})_{2}=2\right] \\\\
&0.1 \times 10 \times \mathrm{n} \text {-Factor }= 0.05 \times 30 \times 2 \\\\
& (\mathrm{n}-\text { Factor })_{\mathrm{A}} =3
\end{aligned}
$$
<br/><br/>
Hence basicity of acid $A$ is 3.
