Chapter 5 Reactions of ionic compounds | Chemistry for VCE Units 1 & 2

ionic compound

a chemical compound that is held in place by ionic bonds

crystal lattice

a three-dimensional arrangement of atoms or ions that repeats to make up a compound

electrolyte

an electrically conductive solution that contains free moving charged ions

electron transfer diagram

a visual representation that shows the movement of electrons between atoms and/or molecules

monoatomic

made from one type of atom

polyatomic

made from more than one type of atom

empirical formula

the simplest whole-number ratio of atoms in a compound

hydrate

an ionic compound that has water molecules surrounding the charged ions

dissociate

break apart into smaller atoms, ions or molecules

net ionic equation

a chemical equation in which electrolytes in aqueous solutions are expressed as dissociated ions

precipitation reaction

a reaction between two soluble ionic substances that forms an insoluble product

precipitate

the solid product formed from a precipitation reaction

spectator ion

an ion that does not participate in a reaction and has the same state and oxidation number as both a reactant and product

double displacement reaction

a chemical reaction that occurs when two reactants exchange cations or anions to form two new products
