How is `O_(3)` estimated quantitatively ?

Explanation

To estimate ozone (O₃) quantitatively, we can follow a systematic method involving a chemical reaction. Here’s a step-by-step solution:

### Step 1: Prepare the Reaction Environment
We start by preparing a solution of potassium iodide (KI) that is buffered with borate. This buffer helps maintain a stable pH during the reaction.

**Hint:** Ensure that the KI solution is in excess to ensure complete reaction with O₃.

### Step 2: React Ozone with Potassium Iodide
