* Solution: A homogeneous mixture where one substance (the solute) dissolves completely into another (the solvent). The resulting mixture has a uniform composition throughout.

* Suspension: A heterogeneous mixture where particles of the solute are dispersed but not dissolved in the solvent. These particles are usually visible and can settle out over time.

Silver nitrate (AgNO₃) is a highly soluble ionic compound. When it dissolves in water, the Ag⁺ and NO₃⁻ ions become evenly distributed throughout the water molecules, forming a clear, colorless solution.

Key points:

* The solution is transparent and homogeneous, meaning you can't see individual particles of silver nitrate.

* Silver nitrate ions are evenly distributed, not just floating around in the water.

Therefore, a mixture of silver nitrate and water is a solution.
