Acids and Bases Nomenclature

Acids have..

Acids have..

• pH <7

• start w H in chemical formula

• ex: H2SO4, HCl, HNO3

Bases have..

• pH >7

• ends w OH in chemical formula

• ex: NaOH, KOH.

rule #1

if anion ends in -ide, acid name has prefix of hydro-, suffix -ic. For example, HCl is hydrochloric acid.

rule #2

if the anion ends in -it'd, the acid name is stem of anion w suffix -ous.

rule #3

if anion ends in -ate, acid name is stem of anion w suffix -ic.

what rules are only for polyatomic atoms?

#2 and #3.

acid to name

write elements symbol, charge in right hand corner, determine what H would need to make 0 net charge, criss cross and drop charges.

base to formula

write symbol for cation and anion, determine cations charge, criss cross.

formula to name

write name of cation, if anion replace ending s -ide, if polyatomic, write as is on PT.
