Sulfur atom is the center atom and there are no charges on atoms in H2SO3 lewis structure. Is MnO2 acidic, basic or amphoteric? They neither turn moist red litmus paper blue nor turn moist blue litmus paper red. (e) a species that can accept a pair of electrons. Bicarbonate (HCO3) is amphoteric, which means it can act as an acid as well as base, depending on what it is reacting with. AlO is an example of an amphoteric oxide. Predict the qualitative pH dependence on the net potential for this reaction (that is, increases, decreases, remains the same). So it HCO3 is both an acid and base, depending on the strength of reacting compound. The amphoteric is the type of the substances that accepts the hydrogen ion or the donates hydrogen in the aqueous solution. It is one of those fictitious acids (like H2CO3) A solution which we call "sulfurous acid" is mostly sulfur dioxide moleucles dissolved in water. E x p l a n a t i o n If the central metal atom is present in its lowest oxidation state, the oxide is basic. In the examples above, you may have noticed that H20 and HCO3 can also exist as acids or bases. 11. Amphoteric substances can be identified by repeatedly removing hydrogen ions from an acid or by repeatedly adding hydrogen ions to a base. When both of them are together, the stronger acid will protonate the weaker acid, which will act as a Brnsted base. Structure of H2SO3. Such species can only accept protons in acid-base reactions.
