Answer 1

The correct answer is a White precipitate of silver chloride is produced.

Key Points

When silver nitrate solution is combined with sodium chloride solution, a white precipitate of silver chloride is generated in addition to the sodium nitrate solution.
Chemical reaction equation:
- \(AgNO\)₃ \((aq)\) \(+\) \(NaCl\) \((aq)\) → \(AgCl(aq)\) \(+ NaNO\)₃ \((aq)\)
It is an illustration of a double displacement reaction.

Additional Information

Double Displacement Reaction
- Chemical reactions known as double displacement reactions occur when the reactant ions move around to create new products. Precipitate production often happens as a result of a double displacement process. Covalent or ionic chemical bonds may be present between the reactant.
- For instance, a white precipitate of barium sulphate quickly forms when a solution of barium chloride and sodium sulphate is combined. These are ionic-based reactions. When the reactants are dissolved in water, they turn into ions, and when ions exchange in the solution, a product molecule is created.
- \(Ba\)²⁺ \((aq) + 2Cl\)^- \((aq) + 2Na\)⁺ \((aq) + SO\) ₄ ^2- \((aq)\) → \(Ba\)²⁺ \((aq) + SO\)₄ ^2- \((aq) + 2Na\)⁺ \((aq) + 2Cl \)^- \((aq)\)
