Question

Which of the following mixtures will act as a buffer solution when dissolved in 50 mL of water ? (A) 0.2 mol of aniline + 0.2 mol of HCl (B) 0.2 mol of aniline + 0.4 mol of NaOH (C) 0.2 mol of NaCl + 0.1 mol of HCl (D) 0.2 mol of aniline + 0.1 mol of HCl

Tardigrade Admin · Accepted Answer

Aniline and its salt with HCl will act as a buffer solution 0.2 mol of aniline + 0.1 mol of HCl =0.1 mol of aniline hydrochloride + 0.1 mol aniline

Q. Which of the following mixtures will act as a buffer solution when dissolved in 50 mL of water ?

0.2 mol of aniline + 0.2 mol of HCl

0.2 mol of aniline + 0.4 mol of NaOH

0.2 mol of NaCl + 0.1 mol of HCl

0.2 mol of aniline + 0.1 mol of HCl

Aniline and its salt with $H Cl$ will act as a buffer solution
$0.2 m o l$ of aniline $+ 0.1 m o l$ of $H Cl$
$= 0.1$ mol of aniline hydrochloride $+ 0.1$ mol aniline

Q. Which of the following mixtures will act as a buffer solution when dissolved in 50 mL of water ?

0.2 mol of aniline + 0.2 mol of HCl

0.2 mol of aniline + 0.4 mol of NaOH

0.2 mol of NaCl + 0.1 mol of HCl

0.2 mol of aniline + 0.1 mol of HCl

Aniline and its salt with HCl will act as a buffer solution 0.2mol of aniline +0.1mol of HCl =0.1 mol of aniline hydrochloride +0.1 mol aniline

$0.2 m o l$ of aniline $+ 0.1 m o l$ of $H Cl$
$= 0.1$ mol of aniline hydrochloride $+ 0.1$ mol aniline
