Concept introduction:
Generally, the chemical compounds are made up of polyatomic ions and the ratio of positive to negative ions present in the substance is expressed as formula of ionic compound. Some elements form monoatomic ions having different charges and to differentiate the two ions, size of the charge of ions is included when naming the ion. A reaction of oxoacids with water induces removal of acid protons and the species that remains keeps the electron belongs to hydrogen atom. Since, the new species formed has one more electron than the entire number of protons in the parent neutral molecule, it accepts a negative charge. Thus, the new species generated is an ion and usually called as oxoanion.
