Is it ionic? no Use prefixes for the subscripts. yes no Does the second ion end with ide? Does it start with hydro-? yes Start with H. Look at oxidation on the second ion, and use that as subscript. no no yes Use the periodic table for oxidation numbers. Use subscripts to make the compound neutral. Name according to the number of carbons. no yes Is it an acid? yes Is it organic? Does it end with -ic? yes Use the common ions table for oxidation numbers. Use subscripts to make the compound neutral. no The second ion ends with –ite. Start with H, and use the oxidation of the –ite as your subscript. The second ion ends with –ate. Start with H, and use the oxidation of the –ate as your subscript. Is it ionic? no no yes Is it an acid? yes no Is it binary? no no yes Change the end of the second ion to –ide. Does the polyatomic ion’s name end with – ate? yes Use the name of the second ion as is. Count each atom and use prefixes. Change the ending of the second atom’s name to –ide. yes Start the name with hydro-, then change the end of the second ion’s name to –ic. Add acid. yes Does the name end with -ide? Is it binary? Count the carbons and name accordingly yes Is it organic? no no Change the end of the polyatomic ion’s name to –ous. Add acid. Change the end of the polyatomic ion’s name to –ic. Add acid.
