• 5.1 Properties of Compounds in Aqueous
  Solutions
• solution a homogeneous mixture of two or more
  substances
• one substance is considered the solvent, the
  medium in which another substance, the solute, is
  dissolved

3

• Ions in Aqueous Solutions Electrolytes

An Ionic Compound,CuCl2, in Water
4
QHow do we know ions are present in aqueous
solutions? AThe solutions conduct
electricity! -They are called ELECTROLYTES -HCl,
CuCl2, and NaCl are strong electrolytes. -They
dissociate completely (or nearly so) into ions.
5
Acetic acid ionizes only to a small extent, so it
is a weak electrolyte. CH3CO2H(aq) ---gt
CH3CO2-(aq) H(aq)
6
Some compounds dissolve in water but do not
conduct electricity. They are called
nonelectrolytes.
Examples include sugar ethanol ethylene glycol
7
B. Water Solubility of Ionic Compounds -If one
ion from the Soluble Compound list is present
in a compound, the compound is water soluble.
