Which will make basic buffer?
a) 100 m L o f 0.1 M HCl + 200 mL of 0.1 M N H 4 O H
b) 100 mL of 0.1 M HCl + 100 mL of 0.1 M NaOH
c) 50 mL of 0.1 M NaOH +25 mL of 0.1 M C H 3 C O O H
d) 100 mL of 0.1 M C H 3 C O O H + 100 mL of 0.1 M NaOH.

A

100 mL of 0.1 M HCl + 100 mL of 0.1 M NaOH

B

50 mL of 0.1 M NaOH + 25 mL of 0.1 M `CH_(3)COOH`

C

100 mL of 0.1 M `CH_(3)COOH` + 100 mL of 0.1 M NaOH

D

100 mL of 0.1 M HCl + 200 mL of 0.1 M `NH_(4)OH`

Text Solution

Verified by Experts

The correct Answer is:
D
Acid-base titration
`underset("10 m mole")(HCl)+underset(20-10)underset("20 m mole")(Na_(4)OH)tounderset("10 m mole")(Na_(4)Cl)`
HCl is limiting reagent
Solution contain `underset((WB))(NH_(4)OH)&underset((SAWB))(NH_(4)Cl)`
The basic buffer will form
