  2. Naming Hydrates • Many solid compounds release water when heated at low temperatures. • In these compounds, called hydrates, water molecules are loosely bonded within the solid crystal at regular intervals. • A common example of a hydrate is: CuSO4 •5H2O • Where the compound is written first, followed by a dot (representing a weak bond) and then the number of water molecules that hydrate the compound • To name a hydrate: • Name the compound (according to the rules previously discussed) • The choose the prefix in the table to the right that indicates the number of water molecules. • Add the word “hydrate” to the end of the prefix. • A common example of a hydrate is: CuSO4 •5H2O Copper(II) sulfate pentahydrate

  3. Naming Hydrates Practice • Name each hydrate: • Li2SO4 ∙ 10H2O • Pb(OH)4 ∙ 7H2O • Cs2CO2 ∙ 2H2O • Write the formula for each hydrate: • vanadium (III) bromide tetrahydrate • strontium nitrate pentahydrate • calcium carbonate trihydrate lithium sulfate decahydrate lead (IV) hydroxide heptahydrate cesium carbonitedihydrate VBr3 ● 4H2O Sr(NO3)2 ● 5H2O CaCO3 ● 3H2O
