The pH of 1 N aqueous solutions of HCl , CH ₃ COOH and HCOOH follows the order:
Options
- AHCl HCOOH CH ₃ OOH
- BHCl = HCOOH CH ₃ COOH
- CCH ₃ COOH HCOOH HCl
- DCH ₃ COOH = HCOOH HCl
Correct answer
C. CH ₃ COOH HCOOH HCl
Step-by-step solution
Stronger the acid, lower is the pH or weaker the acid, higher the pH . The strength of the given acid is in the order HCl HCOOH CH ₃ COOH Hence, their pH is in the order CH ₃ COOH HCOOH HCl
