nitrates soluble
salts with alkali metal ions (group I) are soluble
chloride, bromide, and iodide salts are soluble EXCEPT silver (I), lead (II), and mercury (I)
sulfate salts are soluble EXCEPT barium sulfate, lead (II) sulfate, mercury (I) sulfate, and calcium sulfate
hydroxides with Ba and Ca marginally soluble (kinda sorta soluble)
Most hydroxides are... slightly soluble
sulfides, carbonates, chromates, and sulfates are slightly soluble EXCEPT group I cations and ammonium
salts with ammonium are... soluble
most ionic compounds contain... 2 types of ions
in a precipitation rxn, the precipitate must have... a zero net charge
dilution equation M1V1 = M2V2
mols of solute ARE NOT... determined through dilution
molarity equation M = mols/liters
what is an electolyte a particle that transfers current, charge, etc
nonelectrolyte does not produce ions when dissolved
weak electrolytes partial dissociation; substances that produce lesser ions when dissolved (weak acids, weak bases)
strong electrolytes complete dissociation; substances produce ions when dissolved (soluble salts, strong acids, strong bases)
according to Svante Arrhenius, the conductivity of a solution... depends on the number of ions present
hydration interaction between water molecules and the ions of a salt, causing dilution
differences in solubility of ionic compounds depends on attraction of ions to one another and attraction of ions to water molecules
solute substance dissolved (minority)
solvent liquid/ water (majority)
HCl hydrochloric acid, strong acid
HBr hydrobromic acid, strong acid
HClO4 perchloric acid, strong acid
H2SO4 sulfuric acid, strong acid

carbonate and phosphate are not soluble EXCEPT with sodium, potassium, ammonium
sulfide is only soluble with sodium, potassium, ammonium, barium
hydroxide and oxides are only soluble with sodium, potassium, barium, group I cations
sulfate salts are soluble EXCEPT with calcium, silver, mercury (I), strontium, barium, lead (II)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
