10 " mL of " `H_2O_2` liberates 12.7 g of iodine form an acidic KI solution. Calculate the normality

Explanation

To solve the problem of calculating the normality of the hydrogen peroxide (H₂O₂) solution that liberates iodine (I₂), we can follow these steps:

### Step 1: Understand the relationship between H₂O₂ and I₂
In this reaction, hydrogen peroxide (H₂O₂) acts as an oxidizing agent and liberates iodine from potassium iodide (KI) in an acidic medium. We need to find the normality of H₂O₂ based on the amount of iodine liberated.

### Step 2: Calculate the equivalent weight of I₂
The equivalent weight of iodine (I₂) can be calculated using the formula:
\[
