Solutions and Mixtures

What is a mixture?

• A mixture is a combination of two or more substances that are not chemically bonded together.

• A mixture is a single substance made up of only one type of molecule.

• A mixture is a chemical reaction between two or more elements.

• A mixture is a solution that has been filtered to remove impurities.

What is concentration in the context of solutions?

• The temperature at which a solution boils.

• The amount of solute present in a given volume of solvent or solution.

• The color of the solution when mixed with a solute.

• The pressure exerted by the solute in a solution.

What is a solution?

• A solution is a heterogeneous mixture of two or more substances.

• A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent).

• A solution is a type of chemical reaction.

• A solution is a solid substance that cannot dissolve in any liquid.

What is a heterogeneous mixture?

• A mixture that has a uniform composition and cannot be easily separated.

• A mixture that has a non-uniform composition, where the different components can be seen and separated.

• A mixture that consists of only one type of substance.

• A mixture that is always in a solid state.

What is the difference between a mixture and a solution?

• A mixture is always homogeneous, while a solution can be heterogeneous or homogeneous.

• A mixture can be heterogeneous or homogeneous, while a solution is always homogeneous.

• A mixture is a type of solution that contains only one substance.

• A solution can be separated into its components by physical means.

Can a solution be separated into its components?

• No, solutions cannot be separated.

• Yes, a solution can be separated into its components through physical methods such as evaporation or distillation.

• Only certain solutions can be separated.

• Solutions can only be separated through chemical reactions.

What is saturation in a solution?

• A state where a solution can dissolve more solute

• A condition where a solution can no longer dissolve additional solute at a given temperature and pressure

• A process of heating a solution to increase solubility

• A method of filtering out impurities from a solution

What is an example of a solid solution?

• Bronze, a mixture of copper and tin

• Saltwater, a mixture of salt and water

• Air, a mixture of gases

• Granite, a mixture of minerals

Is air a mixture or a solution?

• Air is a solution of gases.

• Air is a homogeneous mixture of gases.

• Air is a compound of nitrogen and oxygen.

• Air is a heterogeneous mixture of gases.

What is the significance of the solubility of a substance?

• It determines the color of the substance in a solution.

• It indicates how much solute can be dissolved in a solvent at a specific temperature and pressure.

• It affects the boiling point of the solvent.

• It is related to the density of the solute.
