Which will make basic buffer?

$50 m L o f 0.1 M N a O H + 25 m L o f 0.1 M C H_{3} C O O H$
$100 m L o f 0.1 M C H_{3} C O O H + 100 m L o f 0.1 M N a O H$
$100 m L o f 0.1 M H C l + 200 m L o f 0.1 M N H_{4} O H$
$100 m L o f 0.1 M H C l + 100 m L o f 0.1 M N a O H$

Solution

Given,

$100 m l$ of $0.1 M H C l + 200 m l$ of $0.1 M N H_{4} O H$

Therefore, it is a basic buffer.

Hence, option (C) is correct.
