___________________ a substance which dissolves to yield a solution with ions that can conduct electricity
Eg. (NH4)3PO4(s) 3NH4+(aq) + PO43-(aq)
An ______________solution contains only neutral molecules.
These are some guidelines, but there are exceptions:
_______ compounds consisting of a metal and a non-metal are likely to form ionic solutions
Eg. FeCl3(s) Fe3+(aq) + 3Cl(aq)
Eg. (NH4)2Cr2O7(s) 2NH4+(aq) + Cr2O72(aq)
_______________ compounds (AKAcovalentcompounds) made of 2 or more non-metals, especially_________________compounds are likely to be a molecular solution
Eg. ClO2(l) ClO2(aq)
Eg. CH3OH(l) CH3OH(aq) (organic b/c it starts
The _______________________ of a substance is the maximum amount of the substance which can dissolve in a given amount of solvent @ a giventemp.
A solution which has dissolved the “max. amount” of a substance is said to be ____________________.
Once a solution has been saturated the addition of more substance will cause it to sink/float undissolved in the solution.
The _____________________ of a substance is the __________________ concentration of the substance @ a given ______________
The solubility is referred to as the ____________ solubility where the  is expressed as “moles/litre”
A substance is said to form a saturated solution if the dissolved substance is in _____________with some of the __________________ substance.
some undissolved material is present
equil. Exists b/t the dissolved and the undissolved material
Eg. AgBrO3(s) Ag+(aq) + BrO3(aq) Dissolving equation
In the beginning…
AgBrO3(s) Ag+(aq) + BrO3(aq) = dissolving rxn.
Ag+(aq) + BrO3(aq) AgBrO3(s) = ________________ rxn.
AgBrO3(s) Ag+(aq) + BrO3(aq)
