Aqueous solutions of `KOH` and `CH_3COOH` of identical concentrations are provided. is This pair of solutions form a buffer upon mixing

Explanation

To determine whether the aqueous solutions of KOH (potassium hydroxide) and CH₃COOH (acetic acid) form a buffer upon mixing, we can follow these steps:

### Step 1: Identify the nature of the solutions
- KOH is a strong base.
- CH₃COOH is a weak acid.

### Step 2: Understand what a buffer solution is
- A buffer solution is one that resists changes in pH upon the addition of small amounts of acid or base. It typically consists of a weak acid and its conjugate base or a weak base and its conjugate acid.

### Step 3: Analyze the combination of KOH and CH₃COOH
- When KOH (strong base) is mixed with CH₃COOH (weak acid), the strong base will react with the weak acid. The reaction can be represented as:
\[ \text{CH}_3\text{COOH} + \text{KOH} \rightarrow \text{CH}_3\text{COOK} + \text{H}_2\text{O} \]
- This reaction produces potassium acetate (CH₃COOK), which is the conjugate base of acetic acid.

### Step 4: Determine if the resulting solution is a buffer
- After the reaction, we have a solution that contains both the weak acid (CH₃COOH) and its conjugate base (CH₃COOK). This combination meets the criteria for a buffer solution.

### Conclusion
- Therefore, the mixture of KOH and CH₃COOH does indeed form a buffer solution.

### Final Answer
Yes, the pair of solutions forms an acidic buffer upon mixing.
