Get answer: Pyrolusite, MnO_(2), is the main ore from which manganese is produced. The manganese content of the ore may be determined by reducing the MnO_(2) under acetic conditions to Mn^(2+) with the oxalate ion, C_(2)O_(4)^(2), the oxalate ion being oxidised to carbon dioxide during the reaction. The analytical determination is carried out by adding a .
