Weak acid + its salt of strong base

Vedclass · Answer

(D) solution that resists change in $pH$ value upon addition of a small amount of strong acid or base (less than $1\%$) or when the solution is diluted is called a buffer solution.An acidic buffer solution consists of a mixture of a weak acid and its salt with a strong base.$A$ basic buffer solution consists of a mixture of a weak base and its salt with a strong acid.Therefore,a buffer solution can be prepared by mixing a weak acid and its salt with a strong base.

When $0.02 \ mol$ of $NaOH$ is added to $1 \ L$ of a buffer solution,its $pH$ changes from $5.75$ to $5.80$. What is the buffer capacity of the solution?

If the $pH$ of a mixture of $10 \, mL$ of $0.1 \, M \, NH_4OH$ and $10 \, mL$ of $1 \, M \, NH_4Cl$ solution is $8$,the $pK_b$ value of $NH_4OH$ is then closest to

For a weak acid $(HA)$,$pK_a = 4.5$. The $pOH$ of a buffer solution of $HA$ in which $50\%$ of the acid is ionized is:

The $pH$ of a solution at $25\,^oC$ containing $0.10\,M$ sodium acetate and $0.03\,M$ acetic acid is ($pK_a$ for $CH_3COOH = 4.57$)

Assertion : Mixture of $CH_3COOH$ and $CH_3COONH_4$ is an example of acidic buffer.
Reason : Acidic buffer contains equimolar mixture of a weak acid and its salt with weak base.
