Strong electrolytes
fully dissolve and 100% disassociate
Dissociation
The process where a compound, especially an ionic compound or acid, separates into its individual ions when dissolved in a solvent, typically water
What things disassociate?
Ionic compounds, strong acids and strong bases (-OH)
Things that are not separated in an ionic equation
Weak electrolyte, fully dissolve AND PARTIALLY DISSOCIATE
a. Weak Acids (all other acids)
b. Weak Bases (-N)
Nonelectrolytes (not separated in an ionic equation)
FULLY dissolve, but DO NOT DISSOCIATE
Molecular compounds (covalent)
Nitrate and acetate salts
are soluble
Alkali salts and ammonium are
soluble
Halide salts are
soluble, BUT NOT Ag+, Pb 2+, Hg2 2+
Sulfate salts
are soluble, BUT NOT Ba, PB, Hg, Ca, Sr
OH- salts
are insoluble, (Group 1, Ba, Sr, and Ca are SOLUBLE)
Most S2-, CO3 2-, CrO4 2-, PO4 3-, salts
INSOLUBLE
Strong acids
HCl, HBr, HI, HNO3, HClO4, H2SO4 are soluble
SNAP (sodium. nitrate, ammonium and potassium ions)
ALWAYS SOLUBLE WILL NOT FORM A SOLID
