The aqueous solution of which of the following salt will have the lowest pH ?

Options

  1. ANaClO ₃
  2. BNaClO
  3. CNaClO ₄
  4. DNaClO ₂

Correct answer

C. NaClO ₄

Step-by-step solution

aligned & NaClO ₄ Na ⁺+ ClO ₄⁻ & NaClO ₃ Na ⁺+ ClO ₃⁻ & NaClO ₂ Na ⁺+ ClO ₂⁻ & NaClO Na ⁺+ ClO ⁻ aligned In aqueous solution, these compounds decompose into ions. ClO ₄⁻ will most easily abstract proton from water molecules. So it will be most acidic.
