Concentrated `HNO_(3)` reacts with iodine to give:

Options

A. HIO
B. HI
C. `HIO_(2)`
D. `HlO_(3)`

Explanation

To solve the question regarding the reaction of concentrated HNO₃ (nitric acid) with iodine (I₂), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are concentrated nitric acid (HNO₃) and iodine (I₂).

**Hint:** Always start by identifying the substances involved in the reaction.

### Step 2: Understand the Reaction
Concentrated nitric acid is a strong oxidizing agent. When it reacts with iodine, it oxidizes iodine to form iodic acid (HIO₃).

**Hint:** Recognize that strong acids can act as oxidizing agents and can change the oxidation state of elements.

### Step 3: Write the Balanced Chemical Equation
The balanced chemical equation for the reaction can be represented as follows:

\[ 10 \, \text{HNO}_3 + 4 \, \text{I}_2 \rightarrow 8 \, \text{HIO}_3 + 10 \, \text{NO}_2 + 4 \, \text{H}_2\text{O} \]

This shows that 10 moles of nitric acid react with 4 moles of iodine to produce 8 moles of iodic acid (HIO₃), along with nitrogen dioxide (NO₂) and water (H₂O).

**Hint:** Balancing the equation is crucial to understanding the stoichiometry of the reaction.

### Step 4: Identify the Product
From the balanced equation, we can see that the primary product formed is iodic acid (HIO₃).

**Hint:** Look for the products formed in the reaction to answer the question correctly.

### Step 5: Choose the Correct Option
Given the options:
1. HIO
2. HI
3. HIO₂
4. HIO₃

The correct answer is option 4: HIO₃ (iodic acid).

**Hint:** Compare your findings with the provided options to select the correct answer.

### Final Answer
The concentrated HNO₃ reacts with iodine to give iodic acid (HIO₃).
