solute solvent solution

a solution needs to be: (homoogeneous or heterogenous)

homogenous

homogenous mixture of one or more solutes dissolve in a solution

solution

homogenous or heterogenous:

• uniform composition

homogenous

homogenous or heterogenous:

• you cannot see particles in mixture

homogenous

homogenous or heterogenous:

• all components in solvent are evenly distributed

homogenous

can a heterogenous mixture be a solution?

no

can a homogenous mixture be a solution

yes

homogenous or heterogenous:

• non uniform composition

heterogenous

homogenous or heterogenous:

• does not dissolve

heterogenous

homogenous or heterogenous:

• can see particles in substances

heterogenous

homogenous or heterogenous:

• pebbles in water is an example of

heterogenous

substance that gets dissolved is called

(solute / solvent / solution)

solute

present in smaller amounts

(solute / solvent / solution)

solute

substance that does the dissolving

(solute / solvent / solution)

solvent

present in larger amounts

(solute / solvent / solution)

solvent

factors affecting solubility:

• for solids and liquids, if temperature increase; solubility (increases or decreases?)

increases

factors affecting solubility:

• for gasses, if temperature rises; solubility (increases or decreases)

decreases

(unsaturated / saturated / supersaturated)

• contains less than the max amount of solute

unsaturated

(unsaturated / saturated / supersaturated)

• contains max amount of solute

saturated

(unsaturated / saturated / supersaturated)

• requires higher temp to dissolve solute

supersaturated

what is required to dissolve supersaturated solutions

heat

what is known as the universal solvent

water

soluble in water (polar or non-polar)

polar

(polar or non-polar) not soluble in water

non-polar

lipid soluble (polar or non-polar)

non-polar

hydrophobic (polar or non-polar)

polar

hydrophilic (polar or non-polar)

non-polar

polar (hydrophobic or hydrophilic)

hydrophilic

non-polar (hydrophobic or hydrophilic)

hydrophobic

lacks charged regions necessary to interact with water molecules (polar or non-polar)

non-polar

why are non-polar molecules water insoluble

dont have the charged regions necessary to interact with H2O molecules
