Abstract	The study was designed to map out students' problems naming oxo salts following a given formula. Students' responses were collected via written tests and in a group discussion. About 10000 students took part in the investigation which was conducted in three cycles. The result was that many students incorrectly named oxo salts as oxides. These names were enumerations of the three elements contained in a compound in accordance with the nomenclature for binary compounds. Their own names for oxo salts were more helpful to students to find the correct formula than the common names. The majority of students tried to find reasonable solutions to the problems they were given, although many arrived at incorrect answers. It is argued that high school students are more interested in intellectually challenging lessons than one might have thought. The items developed in the study are now available to be used in new situations. It is left to the reader then to decide if the new case is sufficiently analogous to the one described.
