SO2 occurs in the atmosphere primarily from the burning of fossil fuels, but also naturally from volcano eruptions. In M n O, M n has oxidation state of + 2 and is least acidic or most basic and M n 2 O 7 has M n in + 7 oxidation state so it is most acidic and least basic. We have already seen that the Cl − ion does not The main natural sources of sulphur dioxide are volcanoes, forest fires and oceans. It exists widely in nature, mostly from volcanic activity and burning fossil fuels. When NH 4 Cl is dissolved in H 2 O, it separates into NH 4 + ions and Cl − ions. Basic oxides contain metals and react with water to form bases, Chemists classify substances which are neither acidic or basic as neutral. 8. ) This chemistry video explains how to determine if an ionic compound or a salt is acidic, basic, or neutral.
