Question

Balanced chemical equation for the decomposition of solid sodium sulfide in aqueous solution.

Answer 1

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

Step-by-step explanation:

We need to know:

What are decomposition reactions?

• Decomposition reactions are type of reactions in which a compound is broken down into two or more products.

• When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
• When this happens the soluble compound such as ionic compounds ionizes to form ions.
• This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
• For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.

• That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
