Question

An acidic buffer is obtained on mixing :

• A. $100 mL$ of $0.1 M CH _{3} COOH$ and $200 mL$ of $0.1 M NaOH$
• B. $100 mL$ of $0.1 M CH _{3} COOH$ and $100 mL$ of $0.1 M NaOH$
• C. $100 mL$ of $0.1 M HCl$ and $200 mL$ of $0.1 M CH _{3} COONa$
• D. $100 mL$ of $0.1 M HCl$ and $200 mL$ of $0.1 M NaCl$

Answer 1

Answer: (C)

So finally we get mixture of

$CH _{3} COOH + CH _{3} COONa$ that will work like

acidic buffer solution.
