6. Writing the Name of an Acid • STEP 1: Does the acid contain a polyatomic ion? • STEP 2: • If YES to polyatomic, then use NO hydro- to begin the name. • If NO to polyatomic, then YES use hydro- to begin the name. • STEP 3: • If hydro- is used, then the name ends with –ic. • If hydro is NOT used, then look closely at the polyatomic ion. • If the ion is an “-ate” ion, then the name ends with –ic. • If the ion is an “-ite” ion, then the name ends with –ous.

8. Writing the Formula of an Acid • STEP 1: Hydrogen is ALWAYS the first element in the formula of an acid. • STEP 2: • If HYDRO begins the name of the acid, then NO polyatomic ion is present. Simply use the monatomic ion signaled by the acid name. • If HYDRO does NOT begin the name of the acid, then ,YES, a polyatomic ion is present. Use the ending of the acid to help you to determine if the ion is an –ate or –ite version. • STEP 3: • Criss-cross the charges of the hydrogen ion (+1) and the monatomic or polyatomic ion.
