Electrolytes |
Substances the release ions when dissolved in water. Also called, dissociation or ionization. |
|
|
Nonelectrolytes |
Substances that do not dissociate in water. Do not conduct electricity. |
|
|
Strong electrolytes |
Dissociate completely into ions in water. Conduct electricity well. Examples: NaCl and HCl |
|
|
Weak electrolytes |
Do not dissociate completely into ions in water. Do not conduct electricity well. Example: acetic acid. |
|
|
Ionic compounds |
- conduct electricity - electrolytes - made of cations and anions (exist in electrical neutrality) - Crystal lattice structure - salts - when soluble -> turns into ions. |
|
|
Molecular compounds |
- 2 or more different non metals - no ions - no overall charge - exist as discrete units of atoms - non-electrolytes |
|
|
Ionic compound properties |
- Crystalline solids - hard, brittle solids - very high melting point - very high boiling point - high density - strong electrolyte in aq solution - electrical conductivity good when compound is molten.
|
|
|
Molecular compound properties |
- gas, liquid, or solid - soft solid - low melting point - low melting point - low density - weak electrolyte on non-electrolyte in aq solution. - electrical conductivity poor in pure form. |
|
|
Name the 8 transition metals that can form ions of multiple charges. |
Cr (chromium) Mn (manganese) Fe (iron) Co (cobalt) Cu (copper) Hg (Mercury) Sn (tin) Pb (lead) |
|
|
Monatomic ions |
Charged species of single atoms |
|
|
Monatomic ions |
Charged species of single atoms |
|
|
Polyatomic ions |
Consists of a group of atoms with an overall net charge |
|
|
Oxoanions |
Polyatomic ions that contain oxygen attached to some other element. Most polyatomic ions are oxoanions. |
|
|
Acid |
A substance that loses a H+ when reacting with water. - recognized by formulas that start with H (HCl) - water ionizes acids to form ions. |
|
|
Bases |
Substances that accept the H+ of an acid - bases dissociate to form hydroxide ions. |
