Problem Details

Starting with common oxyanions that end in ate (chlorate, ClO3-), adding one O atom or removing two O atoms forms other common or representative oxyanions. Adding one oxygen atom to an oxyanion that ends in ate results in oxyanions that begin with per and end with ate (perchlorate, ClO4-). Removing one O atom from oxyanions that end in ate gives oxyanions that end in ite (chlorite, ClO2-). Removing one more O atom gives anions that begin with hypo and end with ite (hypochlorite, ClO-).
