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

Q. An acidic buffer is obtained on mixing :

$100 m L$ of $0.1 MC H_{3} COO H$ and $200 m L$ of $0.1 MN a O H$

$100 m L$ of $0.1 MC H_{3} COO H$ and $100 m L$ of $0.1 MN a O H$

$100 m L$ of $0.1 M H Cl$ and $200 m L$ of $0.1 MC H_{3} COON a$

$100 m L$ of $0.1 M H Cl$ and $200 m L$ of $0.1 MN a Cl$

So finally we get mixture of

$C H_{3} COO H + C H_{3} COON a$ that will work like

acidic buffer solution.

Q. An acidic buffer is obtained on mixing :

100mL of 0.1MCH3​COOH and 200mL of 0.1MNaOH

100mL of 0.1MCH3​COOH and 100mL of 0.1MNaOH

100mL of 0.1MHCl and 200mL of 0.1MCH3​COONa

100mL of 0.1MHCl and 200mL of 0.1MNaCl

So finally we get mixture of CH3​COOH+CH3​COONa that will work like acidic buffer solution.

$100 m L$ of $0.1 MC H_{3} COO H$ and $200 m L$ of $0.1 MN a O H$

$100 m L$ of $0.1 MC H_{3} COO H$ and $100 m L$ of $0.1 MN a O H$

$100 m L$ of $0.1 M H Cl$ and $200 m L$ of $0.1 MC H_{3} COON a$

$100 m L$ of $0.1 M H Cl$ and $200 m L$ of $0.1 MN a Cl$

So finally we get mixture of

$C H_{3} COO H + C H_{3} COON a$ that will work like

acidic buffer solution.
