The neutralization occurs when 10mL of 0 . 1M acid ' A ' is allowed to react with 30mL of 0 . 05M base M (OH) _ 2 . The basicity of the acid ' A ' is [ M is a metal]

Correct answer: 3 Let basicity of acid is x A + M (OH) _ 2 ⟶ [Salt + Water] At complete neturization. Milli eq. of acid = Milli eq. of base n[0 . 1 × 10] = 2[0 . 05 × 30] n = 3

The neutralization occurs when

10mL

0 . 1M

acid '

A

' is allowed to react with

30mL

0 . 05M

base

M{\left(OH\right)}_{2}

. The basicity of the acid '

A

' is
[

M

is a metal]

Correct answer

Step-by-step solution

Let basicity of acid is $x$

$A + M{\left(OH\right)}_{2} ⟶ \left[Salt + Water\right]$

At complete neturization.

Milli eq. of acid = Milli eq. of base

$n\left[0 . 1 \times 10\right] = 2\left[0 . 05 \times 30\right]$

$n = 3$
