Yes, an aqueous solution of copper sulfate is a homogeneous mixture because it consists of a single phase where the copper sulfate is uniformly dissolved in water, resulting in a uniform composition throughout the solution.
Sodium nitrate dissolves completely in water to form a homogenous mixture, where the sodium and nitrate ions are uniformly distributed throughout the solution. Therefore, it is considered a solution, not a mixture.
An aqueous solution of sodium chloride is best classified as a saltwater solution. Sodium chloride, or table salt, dissolves in water to form a clear, colorless solution.
Mouthwash is typically a homogeneous mixture. This means that the components are evenly distributed throughout the solution and the mixture has a uniform composition.
A dilute aqueous solution of potassium nitrate would be classified as an electrolyte due to the presence of potassium ions (K+) and nitrate ions (NO3-) that can conduct electricity when dissolved in water.
No, a solution is a homogeneous mixture composed of two or more substances. It is a combination in which one substance is dissolved in another, with the components being evenly distributed at a molecular level.
