Term
Colloid
Definition
A sloution in which the solute particles are too small to be seen, but are larger than ions, atoms, or molecules
Term
Concentrated solution
Definition
a solition in which a large amount of soulute is dissolved
Term
Decant
Definition
the process of seperating a suspension by allowing the suspended material to settle out, then pouring off the clear liquid
Term
Dilute Solution
Definition
a soultion that has a small amout of dissolved solute
Term
Filtrate
Definition
the clear liquid that passes through the holes of a filter
Term
Filtration
Definition
the process of searating the parts of a suspenstion by holding back the suspended material, while the clear liquid passes through the small pores of holes of a filter
Term

Definition
Able to be mixed or disolved
Term
Polar Molecule
Definition
a molecule with poitive and negative ends
Term
Polar Solvent
Definition

the material held back by a filter
Term
Saturated Solution
Definition
a solutuion in which no more solute can dissolve
Term
Sediment
Definition
the material that settles out of a suspension
Term
Solubility
Definition
the amount of solute that can dissolve
Term
Sloute
Definition
the part of a solution that is present in a lesser amount. it is the material that is dissolved
Term
Solution
Definition
a homogenious mixture of a slite in a solvent
Term
Solvent
Definition
the part that dissolves the solute. The solvent forms the largest part of the sloution
Term
Supersaturated Solution
