Substance that is dissolved
Solute
Substance that does the dissolving
Solvent
A homogeneous mixture of two or more substances in single physical state
Solution
It means same composition all the way through
Homogenous
Two or more substances not bonded together
Mixture
What are the three physical states
So.id liquid and gas
Solutions are generally…..
Transparent
Solute particles are ….
Ions or molecules
Solutions don’t……. When left standing
Seperate
Amount of solute in a given amount of solvent or solution
Concentration
Little bit of solute compared to amount of solvent
Dilute
Concentration is described in two ways…
Qualitatively
Quantititatively
Comparing amounts without being exact
Qualitative concentration
Lots of solute compared to amount of solvent
Concentrated
It’s an exact measurement of the amount of solute and solvent
Quantitative concentration
Quantitative concentration is expressed in two ways
Molarity (M)
molality (m)
It’s the number of moles of a solute per liter of solution
Molarity
m = ….
mol
m = ——
L
Molality M ==
