Statement 1: Equal volumes of 1 M - HCl solution and 1 M - NaOH solution is required for complete reaction with the same mass of KHC₂O₄.
Statement 2: KHC₂O₄ is amphoteric and it can lose or gain one proton.

Question

Statement 1: Equal volumes of 1 M - HCl solution and 1 M - NaOH solution is required for complete reaction with the same mass of KHC₂O₄.

Statement 2: KHC₂O₄ is amphoteric and it can lose or gain one proton.

With NaOH, KHC₂O₄ acts as a monoacid (HC₂O₄⁻ → C₂O₄²⁻, n = 1); with HCl it acts as a monobasic species (HC₂O₄⁻ → H₂C₂O₄, n = 1). Equal moles react in both cases, so equal volumes of 1 M acid and 1 M base are consumed - I is correct. II is correct and is precisely why the n-factor is 1 on both sides, so II explains I. Hence (a).
