Solutions: Soluble Vs. Insoluble

What is a solvent?

• A substance that dissolves a solute, resulting in a solution.

• A type of chemical reaction that produces heat.

• A solid that cannot dissolve in any liquid.

• A mixture of two or more substances that cannot be separated.

What is the effect of pressure on the solubility of gases?

• Increasing pressure decreases the solubility of gases in liquids.

• Increasing pressure has no effect on the solubility of gases in liquids.

• Increasing pressure increases the solubility of gases in liquids.

• Increasing pressure only affects the solubility of solids, not gases.

What is saturation in a solution?

• Saturation occurs when no more solute can dissolve in the solvent at a given temperature.

• 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 when a solution has reached its boiling point.

What does it mean for a substance to be insoluble?

• A substance that can dissolve in a solvent.

• A substance that can be easily mixed with other substances.

• An insoluble substance is one that cannot dissolve in a solvent.

• A substance that changes its state when mixed with a solvent.

What is an electrolyte?

• A substance that produces ions when dissolved in water, allowing it to conduct electricity.

• A type of acid that neutralizes bases.

• A solid that cannot conduct electricity under any circumstances.

• A gas that forms when water is heated.

What is the difference between a homogeneous and heterogeneous mixture?

• A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.

• A homogeneous mixture contains multiple substances that are easily separated, while a heterogeneous mixture is a single substance.

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

• A homogeneous mixture has distinct layers, while a heterogeneous mixture is completely mixed.

How can you determine if a substance is soluble or insoluble?

• By conducting experiments or consulting solubility charts.

• By observing the color of the substance.

• By measuring the temperature of the substance.

• By checking the pH level of the substance.

Give an example of a soluble substance.

• Salt

• Sugar

• Sand

• Oil

Give an example of an insoluble substance.

• Sodium chloride (NaCl)

• Silver chloride (AgCl)

• Potassium nitrate (KNO3)

• Calcium sulfate (CaSO4)

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.
