What is the definition of solution? |
A solution is a mixture of substances that can completely dissolve in a liquid or gas. |
|
|
The substance that dissolves in the liquid or gas to form a solution is known as? |
Solute |
|
|
The liquid or gas that dissolves the substance is called? |
Solvent |
|
|
______ + ______ = solution |
Solute + solvent = solution Eg. Sugar (solute) Water (solvent) Sugared water (solution) |
|
|
Properties of solutions are? |
1) A homogeneous mixture 2) When left to stand, no separation of solute and solvent. (The solute particles do not settle at the bottom of the mixing container.) 3) Hence, when filtration is carried out, no residue can be found on the filter paper. |
|
|
What is the definition of a suspension? |
A suspension is a mixture of substances that cannot dissolve in a liquid or gas and remains suspended in the mixture. |
|
|
______ + ______ = suspension |
Insoluble substance (cannot dissolve) + liquid = suspension Eg. Fine sand (insoluble substance) Water (liquid) Sandy water (suspension) |
|
|
Properties of suspentions are? |
1) A heterogeneous or a non- homogeneous mixture. (Substances cannot dissolve in the solvent) 2) When left to stand, insoluble particles settle at the bottom of the mixing container. 3) Hence, when filtration is carried out, a residue can be found on the filter paper. |
|
|
What is the similarity between solutions and suspensions? |
Both are mixtures in which 2 or more substances are mixed together. |
|
|
What are the differences between solutions and suspensions? |
|
|
|
What is solubility of a substance? |
Solubility of a substance is the maximum amount of substance (solute) that can dissolve in a given volume of a solvent at a given temperature. |
|
|
What happens when maximum amount of solute is dissloved? |
The solution is saturated when excess solute added will not dissolve. |
|
|
What factors that affect the solubility? |
1) Nature (type) of solute. (Salt, sugar) 2) Nature of solvent (oil, water) 3) Temperature of solvent (Higher temperature, higher solubility) |
|
|
Solubility is? |
How much i can dissolve |
|
|
What is rate of dissolving? |
Rate of dissolving or speed of dissolving refers to how fast a substance can dissolve in a given volume of solvent. |
|
|
What factors that affect rate of dissolving? |
1) Temperature of solvent 2) Rate of stirring 3) Size of solute particles |
