Nomenclature Practice Types I, II, & III Acids and Hydrates

Directions A compound’s name or formula will be presented. For each you should determine the category of compound. i.e. Type I, II, III, Binary Acid, Oxyacid, or Hydrate If the formula is given determine it’s name If the name is given determine it’s formula.

Reminders Type I Column IA, IIA, Ag, Zn & Al Name both ions Charges total to zero Type II The rest of the metals Cation named with roman numeral (RN = charge) Charges total to zero Type III Nonmetals with nonmetals Named with prefixes

Reminders Acids ~ H +1 is the cation Oxyacids – contain oxygen To name ~ remove the ‘ate’ add ‘ic acid’ To write formula ~ charges must total to zero Binary acids – two elements (no oxygen) To name ~ use ‘hydro’ prefix & add ‘ic acid To write formula ~ charges must total to zero Hydrates Ionic compounds named as normal with a ‘prefix hydrate’ added as a suffix
