सही उत्तर · विकल्प 2
\( 100\text{ mL} \) of \( 0.1\text{ M}\text{ HCl} + 200\text{ mL} \) of \( 0.1\text{ M}\text{ NH}_4\text{OH} \)
व्याख्या
A basic buffer consists of a weak base and its salt with a strong acid. In option 2, \( 100\text{ mL} \) of \( 0.1\text{ M}\text{ HCl} \) neutralizes \( 100\text{ mL} \) of \( 0.1\text{ M}\text{ NH}_4\text{OH} \), leaving \( 100\text{ mL} \) of unreacted \( 0.1\text{ M}\text{ NH}_4\text{OH} \) and \( 100\text{ mL} \) of \( \text{NH}_4\text{Cl} \), forming a basic buffer.
