Question

A buffer solution can be prepared from a mixture of (A) sodium acetate and acetic acid in water (B) sodium acetate and HCl in water (C) ammonia and ammonium chloride in water (D) ammonia and sodium hydroxide in water

Tardigrade Admin · Accepted Answer

CH3COOH + CH3COONa = Buffer solution CH3COONa + HCl longrightarrow CH3COOH + NaCl If HCl is taken in limited quantity, final solution will have both CH3COOH and CH3COONa needed for buffer solution. Ammonia and ammonium chloride forms basic buffer

Q. A buffer solution can be prepared from a mixture of

sodium acetate and acetic acid in water

sodium acetate and $H Cl$ in water

ammonia and ammonium chloride in water

ammonia and sodium hydroxide in water

$C H_{3} COO H + C H_{3} COON a$ = Buffer solution
$C H_{3} COON a + H Cl ⟶ C H_{3} COO H + N a Cl$
If $H Cl$ is taken in limited quantity, final solution will have both $C H_{3} COO H$ and $C H_{3} COON a$ needed for buffer solution.
Ammonia and ammonium chloride forms basic buffer
