What is the nature of the resulting solution prepared from 100 m l of 0.2 M H 2 S O 4 added to 100 m l of 0.2 M N a O H .

Options

  1. ANeutral
  2. BAcidic
  3. CBasic
  4. DSlightly basic

Correct answer

B. Acidic

Step-by-step solution

M.eq. of 0.2M H 2 S O 4 = 2 × 0.2 M 1000 × 100 = 0.04 M . e q . o f . 2 M N a O H = 0.2 1000 × 100 = 0.02 left [ H + ] = 0.04 - 0.02 = 0.02 . Total volume = 200 = . 02 200 = . 0001 = 1 0 - 4 M p H = 4 .
