The pH of 1 N aqueous solutions of HCl, \(C{H}_{3}COOH\) and HCOOH follows the order:
Q1 FREE PREVIEW
The pH of 1 N aqueous solutions of HCl, \(C{H}_{3}COOH\) and HCOOH follows the order:
✓ Correct answer: c)
\(C{H}_{3}COOH>HCOOH>HCl\)
Explanation
Strong acid HCl fully ionizes, giving the lowest pH. Weak acids HCOOH and CH₃COOH partially ionize, with CH₃COOH being weaker. Order: HCl < HCOOH < CH₃COOH. Correct answer: (C).
