Chemistry Unit 3 - Solubility

The ability of a substance to dissolve in another substance

In a solution, the substance in which the solute dissolves.

substance that is dissolved

positive side of water molecules pulls neg charged chloride ion off

negative side of water molecules pull pos charged sodium ion

polar molecules and ionic compounds

most covalent compounds don't dissolve in water unless there's a polar portion.

sugars and alcohols

some ionic compounds have lower electrochemical attraction

split to form electrolytes

some ionic compounds have higher electrochemical attraction

precipitate out the solution

a solution that cannot dissolve any more solute under the given conditions

any solution that can dissolve more solute at a given temperature

the separation of ions that occurs when a solid ionic compound dissolves

any process that results in the formation of an ion

break apart

will not dissolve

will not break apart

do not break apart

the attractions between molecules (cations, anions) of the solute and the solvent

color of precipitates

color of flame tests

adding unknown reagents to unknown solutions

increase ksp = increase solubility

most [ ] an ion can have without ppt

the concentration of a saturated solution at a certain temp

when a solution is at saturation it is at equilibrium

ppt forms

no ppt

equlibrium

moles / volume

mass / volume

a substance that dissolves in water to give a solution that conducts electric current

disassociates into ions

A positively charged ion

A negatively charged ion

when strong acids and bases are put into water and break apart
