The pH of 0.1 M aqueous solutions of NaCl, CH3COONa and NH4Cl will follow the order

Question

The pH of 0.1 M aqueous solutions of NaCl, CH3COONa and NH4Cl will follow the order (A) NaCl < CH3COONa < NH4Cl (B) NH4Cl < NaCl < CH3COONa (C) NH4Cl < CH3COONa < NaCl (D) NaCl < NH4Cl < CH3COONa

Tardigrade Admin · Accepted Answer

NaCl (NaOH + HCl) is a neutral salt, NH4Cl(HCl + NH4OH) is an acidic salt while CH3COONa(CH3COOH + NaOH) is a basic salt. The value of pH of acidic salt is less than 7, while for neutral salt pH value is equal to 7 and for basic salt pH value is greater than 7. Thus, the increasing order of pH 0.1 M aqueous solutions of NaCl,CH3COONa and NH4Cl will be NH4Cl < NaCl < CH3COONa

Q. The $p H$ of $0.1 M$ aqueous solutions of $N a Cl$ , $C H_{3} COON a$ and $N H_{4} Cl$ will follow the order

$N a Cl < C H_{3} COON a < N H_{4} Cl$

$N H_{4} Cl < N a Cl < C H_{3} COON a$

$N H_{4} Cl < C H_{3} COON a < N a Cl$

$N a Cl < N H_{4} Cl < C H_{3} COON a$

Q. The pH of 0.1M aqueous solutions of NaCl, CH3​COONa and NH4​Cl will follow the order

NaCl<CH3​COONa<NH4​Cl

NH4​Cl<NaCl<CH3​COONa

NH4​Cl<CH3​COONa<NaCl

NaCl<NH4​Cl<CH3​COONa

Q. The $p H$ of $0.1 M$ aqueous solutions of $N a Cl$ , $C H_{3} COON a$ and $N H_{4} Cl$ will follow the order

$N a Cl < C H_{3} COON a < N H_{4} Cl$

$N H_{4} Cl < N a Cl < C H_{3} COON a$

$N H_{4} Cl < C H_{3} COON a < N a Cl$

$N a Cl < N H_{4} Cl < C H_{3} COON a$
