Options
- A. HCl HCOOH CH _3 OOH
- B. HCl = HCOOH CH _3 COOH
- C. CH _3 COOH HCOOH HCl
- D. CH _3 COOH = HCOOH HCl
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
