Question
Which will make basic buffer?
Options
50 mL of 0.1 M NaOH + 25 mL of 0.1 M CH3COOH
100 mL of 0.1 M CH3COOH + 100 mL of 0.1 M NH4OH
100 mL of 0.1 M HCI + 200 mL of 0.1 M NH4OH
100 mL of 0.1 M HCI + 100 mL of 0.1 M NaOH

Solution
100 mL of 0.1 M HCI + 200 mL of 0.1 M NH4OH
Explanation:
Basic buffer is the solution which has weak base and its salt
\[\ce{\underset{200 ml}{NH4OH} + \underset{100 ml}{HCl} -> \underset{Salt}{NH4Cl} + H2O + \underset{(100 ml weak base)}{NH4OH}}\]
