The hydrolysis of sodium carbonate involves

Options

A. Reaction between `Na^(+)` and water
B. Reaction between `Na^(+)` and water
C. Reaction between `CO_(3)^(2-)` and water
D. Reaction between `CO_(3)^(-2)` and `H^(+)`

Answer

To solve the question regarding the hydrolysis of sodium carbonate (Na2CO3), we will follow these steps:

### Step 1: Write the chemical formula for sodium carbonate.
Sodium carbonate is represented by the formula Na2CO3.

### Step 2: Understand the hydrolysis process.
When sodium carbonate undergoes hydrolysis, it reacts with water (H2O) to produce sodium hydroxide (NaOH) and carbonic acid (H2CO3).

### Step 3: Write the balanced chemical equation.
The balanced equation for the hydrolysis of sodium carbonate can be written as:
\[ \text{Na}_2\text{CO}_3 + \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2\text{CO}_3 \]

### Step 4: Identify the ions involved in the reaction.
In this reaction, the ions involved are:
- Sodium ions (Na⁺)
- Carbonate ions (CO3²⁻)
- Hydroxide ions (OH⁻)
- Carbonic acid (H2CO3) is formed as a product.

### Step 5: Analyze the options given in the question.
The question likely provides multiple options regarding the ions involved in the hydrolysis of sodium carbonate. We need to identify which ions are present in the hydrolysis reaction.

### Step 6: Determine the correct answer.
From the hydrolysis reaction, we can conclude that:
1. Sodium ions (Na⁺) are produced.
2. Carbonate ions (CO3²⁻) react with water.
3. Hydroxide ions (OH⁻) are produced.
4. Carbonic acid (H2CO3) is formed.

Based on this analysis, the correct answer would be the option that includes the carbonate ion (CO3²⁻) and water (H2O) as involved in the hydrolysis process.

### Final Answer:
The correct answer is the option that includes CO3²⁻ and H2O, which corresponds to the hydrolysis of sodium carbonate.
