Question

Explain buffer solution in hindi.

Answer 1

buffer solution aisa solution hota h jo Ph change ko resist karta h . agar buffer solution m thoda so acid ya base daale toh Ph change nhi hota
buffer solution banaane k liye solution m weak acid aur uska conjugate base hona chahiye ya weak base ayr uska conjugate acid hona chahiye.
example of acidic buffer solution - CH3COOH + CH3COONa ( here Na is spectator, iska koi role nhi h )

Answer 2

$\textbf{\large{Answer -}}$

$\textbf{Buffer Solution :}$

The solution which resist any change in it's pH value by adding small amount of acid or bases are known as buffer solution.

$\textbf{Types of buffer solution :}$

1. Solution of single substance
2. Solution of mixture substance

$\textbf{Solution of single substance :}$

Solution of salt of weak acid and weak base will act as a buffer solution.

Example : $CH_{3}COONH_{4}, (NH_{4})_{2}CO_{3}, (NH_{4})_{2}S$

$\textbf{Solution of mixture substance :}$

It is of two types i.e., acidic buffer solution and basic buffer solution.

• $\textbf{Acidic buffer solution :}$

It is a solution of weak acid and the salt of this weak acid with strong base.

Example -

1. $CH_{3}COOH + CH_{3}COONa$
2. $HCN + NaOH$
3. $H_{2}S + K_{2}S$
4. $H_{2}CO_{3} + Na_{2}CO_{3}$

• $\textbf{Basic buffer solution :}$

It is a solution of weak base and the salt of this weak base with strong acid.

Example -

1. $NH_{4}OH + NH_{4}Cl$
2. $Mg(OH)_{2} + MgSO_{4}$
