What happens when Sodium Sulphate reacts with Barium Chloride solution.

Explanation

To understand what happens when sodium sulfate reacts with barium chloride solution, we can break down the reaction step by step.

### Step 1: Identify the Reactants
The reactants in this reaction are sodium sulfate (Na₂SO₄) and barium chloride (BaCl₂). Both of these compounds are in aqueous solution.

### Step 2: Determine the Type of Reaction
This reaction is classified as a double displacement reaction (also known as a double replacement reaction). In this type of reaction, the ions of the reactants exchange places to form new products.

### Step 3: Write the Ionization of Reactants
When sodium sulfate and barium chloride dissolve in water, they dissociate into their respective ions:
- Sodium sulfate dissociates into 2 sodium ions (Na⁺) and 1 sulfate ion (SO₄²⁻).
- Barium chloride dissociates into 1 barium ion (Ba²⁺) and 2 chloride ions (Cl⁻).

The ionization can be represented as:
- Na₂SO₄ (aq) → 2 Na⁺ (aq) + SO₄²⁻ (aq)
- BaCl₂ (aq) → Ba²⁺ (aq) + 2 Cl⁻ (aq)

### Step 4: Exchange of Ions
In the double displacement reaction, the sodium ions (Na⁺) will combine with the chloride ions (Cl⁻) to form sodium chloride (NaCl), and the barium ions (Ba²⁺) will combine with the sulfate ions (SO₄²⁻) to form barium sulfate (BaSO₄).

### Step 5: Write the Products
The products of the reaction can be written as:
- 2 NaCl (aq) (sodium chloride)
- BaSO₄ (s)

### Step 6: Identify the Precipitate
Barium sulfate (BaSO₄) is insoluble in water, which means it will precipitate out of the solution as a solid. This precipitate is typically white in color.

### Step 7: Write the Balanced Chemical Equation
The balanced chemical equation for the reaction can be written as:
\[ \text{Na}_2\text{SO}_4 (aq) + \text{BaCl}_2 (aq) \rightarrow 2 \text{NaCl} (aq) + \text{BaSO}_4 (s) \]

### Final Answer
When sodium sulfate reacts with barium chloride solution, a double displacement reaction occurs, resulting in the formation of sodium chloride in solution and barium sulfate as a white precipitate.
