Notes
The student will:Define Solubility as a
Characteristic Property of MatterConstruct a solubility graphMake a scatter plot and
accurately determine the “Line of Best Fit”
SolventSoluteSolubilityMixtureSolutionSaturation Point
The liquid component of a solution (water when testing solubility) it can be any liquid
The solid component of a solution, this dissolves into the solution ▪ Salt into water
(saltwater)
A characteristic property of matter expressed as the maximum number of grams of a solute that will dissolve into 100 mL of a solvent at a specified temperature
The combination of two or more substances that are not chemically combined.
Characteristics:▪ Easily separated by:▪Using a Filter▪Evaporation▪ Two Classifications▪Homogeneous – Look the same
throughout▪Heterogeneous – Different compounds
in the mixture can easily be seen
A Homogeneous mixture when a solute(solid) is completely dissolved in a solvent (liquid) All particles of each
(Solute and Solvent) are evenly distributed throughout the solution.▪ Solids (alloys)▪ Liquids (Lemonade)▪ Gas (air)
The point where no more solute will dissolve in a solvent Solute settles at
bottom of solution Where the x axis point
and the y axis point intersect is called the “Saturation Point” for a given substance
Solubility can be used to identify substances.
The point at which the maximum amount of a solute dissolves in a solvent is called the saturation pointWhere x intersects y on the graph
Solubility can be used to identify substances.Total saturation is when solute
settles at the bottom of a solution
Solubility can be used to identify substances.Over saturation is when more
solute dissolves than would at room temperature▪Super sweet Mc D’s Ice Tea
Solubility can be used to identify substances.The more surface area a solute
has the easier it dissolves into a solvent
Solubility can be used to identify substances.Surface area can be increased
by crushing a solute into smaller pieces
Remember:Best ways to increase rate a
solute dissolves▪Increase surface area▪Surface area can be increased by crushing a solute into smaller pieces
Remember:Best ways to increase rate a
solute dissolves▪Increasing temperature
Remember:Best ways to increase rate a
solute dissolves▪Increase rate of mixing
