Mixtures and Solutions

Can a solution be separated by physical means?

• Yes, solutions can be separated by physical means.

• No, solutions cannot be separated by physical means because the components are evenly mixed at the molecular level.

• Yes, but only under certain conditions.

• No, solutions can only be separated by chemical means.

What is the difference between a solution and a mixture?

• A solution is a heterogeneous mixture where components can be seen and separated.

• A solution is a homogeneous mixture where components are evenly distributed, while a mixture can be heterogeneous.

• A solution contains only one component, while a mixture contains multiple components that cannot be separated.

• A solution is always a solid, while a mixture can be a liquid or gas.

What happens to salt when it is dissolved in water?

• The salt sinks to the bottom of the water.

• The salt dissolves and mixes evenly with the water, forming a solution.

• The salt forms a solid layer on the surface of the water.

• The salt evaporates into the air.

Give three examples of solutions.

• Lemonade, coke, and salt water

• Sugar, flour, and water

• Oil, vinegar, and milk

• Sand, gravel, and dirt

What is the role of temperature in dissolving a solute?

• Increasing the temperature generally decreases the solubility of solids in liquids.

• Increasing the temperature generally increases the solubility of solids in liquids, allowing more solute to dissolve.

• Temperature has no effect on the solubility of solids in liquids.

• Higher temperatures make solids dissolve slower in liquids.

Is oil and water an example of a solution? Why or why not?

• Yes, oil and water form a solution because they mix evenly.

• No, oil and water do not form a solution because they separate from each other and do not mix evenly.

• Yes, oil and water can form a solution under certain conditions.

• No, oil and water form a solution but only at high temperatures.

What is saturation in the context of solutions?

• Saturation occurs when a solution can no longer dissolve additional solute at a given temperature and pressure.

• Saturation is the point at which a solution becomes too concentrated to hold any more solute.

• Saturation refers to the maximum amount of solvent that can be added to a solute.

• Saturation is the process of mixing two liquids until they become homogeneous.

What is a solution?

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

• A solution is a homogeneous mixture of two or more substances where the individual components can be seen.

• A solution is a mixture that can be separated by filtration.

• A solution is a homogeneous mixture of two or more substances where the individual components cannot be seen or separated.

What is a solute?

• A substance that is dissolved in a solvent to form a solution.

• A liquid that dissolves a solute.

• A mixture of two or more substances.

• A solid that cannot dissolve in any liquid.

What is a homogeneous mixture?

• A mixture in which the composition is uniform throughout.

• A mixture that contains different substances that are easily distinguishable.

• A mixture that has a variable composition and can be separated by physical means.

• A mixture that is always in a solid state.
