The neutralization occurs when 10   mL of 0 . 1   M 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]

Correct answer

3

Step-by-step solution

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
