Answer
$0.10mol$ $HCl$ wouldn't form a buffer with 1L of $0.20M$ $ CH_3COOH$.
Work Step by Step
- A buffer needs:
1. An acid, so it can neutralyze added bases: $CH_3COOH$.
2. A base, so it can neutralyze added acids: Missing.
Therefore, $HCl$ and $CH_3COOH$ (Two acids), are not capable of making a buffer.
