Question: what are oxoacids and oxoanions?
Answer: Many acids consist of protons bonded to an oxoanion (e.g., HNO3 is H+ bonded to NO3- and H2SO4 is two H+ ions bonded to an SO42- ion). These acids are called oxoacids. To name an oxoacid, one should change the - ate or - ite suffixes of the oxoanions to - ic or - ous respectively and add the word acid at the end.
