Science 6: Solution, Colloids & Suspension

What are the characteristics of colloids?

• Colloids have particles smaller than those in a solution

• Colloids settle out over time

• Colloids do not exhibit the Tyndall effect

• Colloids are mixtures where one substance is dispersed evenly throughout another. They have particles that are larger than those in a solution, but smaller than those in a suspension. Colloids do not settle out and exhibit the Tyndall effect.

What are the types of suspensions?

• The types of suspensions are: 1. Colloidal suspension 2. Emulsion suspension 3. Suspension of fine solid particles in a gas

• 1. Colloidal solution 2. Emulsified mixture 3. Solid dissolved in a liquid

• 1. Suspension of gas in a liquid 2. Suspension of liquid in a gas 3. Suspension of gas in a solid

• 1. Liquid suspension 2. Gas suspension 3. Solid suspension

How do solutes affect solutions?

• Solutes decrease the boiling point of solutions

• Solutes only affect the color of solutions

• Solutes have no effect on solutions

• Solutes can affect the properties of solutions, such as the boiling point, freezing point, and osmotic pressure.

Can you provide examples of applications of colloids in daily life?

• Examples of applications of colloids in daily life include sugar, salt, and vinegar.

• Examples of applications of colloids in daily life include milk, mayonnaise, and paint.

• Examples of applications of colloids in daily life include water, air, and sand.

• Examples of applications of colloids in daily life include glass, metal, and plastic.

What is the difference between a solution, colloid, and suspension?

• A solution is a type of gas, while a colloid is a type of solid, and a suspension is a type of liquid.

• A solution is a type of chemical reaction, while a colloid is a type of physical change, and a suspension is a type of phase transition.

• A solution is a mixture of two or more substances that are evenly distributed, while a colloid is a mixture of two or more substances that are unevenly distributed.

• A solution is a homogeneous mixture where the solute is completely dissolved in the solvent. A colloid is a heterogeneous mixture where the particles are evenly dispersed but not completely dissolved. A suspension is a heterogeneous mixture where the particles settle out over time.

What are the factors that affect the rate of dissolution of a solute in a solvent?

• Smell of the solute

• Distance between the solute and solvent

• Color of the solute

• The factors that affect the rate of dissolution include temperature, surface area of the solute, agitation, and the nature of the solute and solvent.

Explain the concept of solubility and factors affecting it.

• Solubility is the ability of a substance to evaporate in a solvent

• Solubility refers to the ability of a substance to dissolve in a solvent. Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

• Solubility is not affected by temperature, pressure, or the nature of the solute and solvent

• Factors affecting solubility include color, smell, and taste

How can you differentiate between a true solution and a colloidal solution?

• Colloidal solutions have particles smaller than 1 nanometer and do not scatter light

• True solutions have particles larger than 1 nanometer and scatter light

• True solutions have particles smaller than 1 nanometer and do not scatter light, while colloidal solutions have particles between 1-1000 nanometers and scatter light.

• True solutions have particles between 1-1000 nanometers and scatter light
