The pH of 0.1 (M) solution of the following salts increasesin the order:
Correct answer: B. HCl < NH4Cl < NaCl < NaCN
- A. NaCl < NH4Cl < NaCN < HCl
- B. HCl < NH4Cl < NaCl < NaCN
- C. NaCN < NH4Cl < NaCl < HCl
- D. HCl < NaCl < NaCN < NH4Cl
Explanation
pH of NaCl = 7 ; pH of NH4Cl < 7 ; pH of NaCN > 7 and pH of 0.1 (M) HCl = 1
