Science 8-2 unit 4

Solute

 The substance(solid or liquid or a gas) that is dissolved/mixed evenly with/ in a solution

Solution

 A homogeneous mixture where the solute is completely dissolved in the solvent, producing a single uniform appearance

Solvent

The substance(always a liquid) that does the dissolving in a solution

Dissolving

a physical process that happens when a substance(the solute) becomes evenly distributed throughout another liquid(the solvent).

Soluble

A substance is soluble if it dissolves in a particular solvent.

Insoluble

 A substance is insoluble if it does not dissolve in a given solvent. Insoluble materials remain as separate particles, flakes, or layer in the solvent (sand in water)

Mixture

A mixture contains two or more substances combined physically (not chemically)

Each substance keeps its own properties

Homogeneous 

the solute are distributed uniformly and the mixture looks the same throughout

Heterogeneous

 the different solutes are not uniformly distributed and can be seen as distinct parts

Suspension

 a heterogeneous mixture in which solid particles do not dissolve and are dispersed throughout a liquid but are large enough to eventually settle out over time

Concentration

tells us how much stuff(solute) is mixed into a certain amount of liquid(solvent)

The mass of solute that is dissolved in a the volume solvent of “1 milliliter”(g/ml-g/100ml)

Dilute

A solution that contains a relatively small small amount of solute compared to the amount of solvent

Concentrated 

 a solution that contains a relatively large amount of solute compared to the amount of solvent

Saturated solution

completely filled or soaked to capacity, such that no more can be added

Precipitate

the sedimentation of a solid material (a precipitate) from a liquid solution

Unsaturated

a compound or solution can absorb or dissolve more of a substance

Solubility

Solubility is the measure of the ability of a substance, called the solute, to dissolve in another substance, the solvent, to form a homogeneous mixture called a solution(concentration of a saturated solution)

Concentration formula

(gram of solute ÷ volume of solvent )*100
