Increasing order of pH of 0.1 M solution of the following salts is : (A) NaCl < NH4Cl < NaCN (B) NH4Cl < NaCl < NaCN (C) NaCN < NH4Cl < NaCl (D) NaCl < NaCN < NH4Cl |
|
Answer» Correct option: (B) NH4Cl < NaCl < NaCN Explanation: Since NH4Cl is the salt of (WB + SA) so pH < 7, NaCl is salt of (SA + SB) so pH = 7 and NaCN is salt of (WA + SB) so pH < 7. |
