I have no problem with saying that this example of Le Chatelier's principle where the addition of H+ to the equilibrium system could make HSO3- appear to be amphoteric. A substance that has both acidic and basic properties are called an amphoteric substance. Express your answer as a chemical equation. PS: Housecroft and Sharpe, Inorganic Chemistry, p 154: "If an oxide or hydroxide is able to act as either an acid or a base, it is said to be amphoteric. It is one of those fictitious acids (like H2CO3) A solution which we call "sulfurous acid" is mostly sulfur dioxide moleucles dissolved in water. & When we way "sulfurous acid" we must realize that there are no molecules of H2SO3 present. Explain your answer, which must include chemical equations. Could HSO3 - be considered amphoteric? Your [HSO3]- could be considered amphoteric see answers above, but I have only seen amphoteric used when describing the properties of oxides. Basically it means, we say that polyprotic acids are acids with more than one H+. Amphiprotic Species (ions or molecules) - are found on bothsides of the table e.g.) In your case, it will be HSO3^-, but not for the reasons you might think. In order to behave as a Bronsted-Lowry acid it must donate a proton. Here we’re going to say, these compounds, these amphoteric species have something in common. It can act as an acid: Note: "Sulfurous acid", H₂SO₃, is what you might expect to get as the product. Here we’re going to say, these compounds, these amphoteric species have something in common. Understanding how solubility varies with temperature and pressure. View desktop site. The preferred term is amphoteric. In addition, there are some H+ ions and HSO3- ions. No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. - can act as acids (donate H+’s) or as bases (accept H+’s) - to look at an amphiprotic species as an acid, you must find it on the leftside: e.g.) Join Yahoo Answers and get 100 points today. What is amphoteric? Sorry. Could HSO3 - be considered amphoteric? 1.25. H2SO3 does NOT exist in aqueous solution. b) can act as either an acid or a base Amphoteric is a name given to a group pf compounds that can exhibit both alkaline and acidic properties. HSO 4 - can act as acids (donate H +’s) or as bases (accept H +’s) - to look at an amphiprotic species as an acid, you must find it on the left side: e.g.) (Absorb and release H+ ions). They all possess and H+. Do radioactive elements cause water to heat up? What the heck does that mean? Write an equation to show how HSO3− can act as an acid withH2O acting as a base. Mulvaney predicts a 'peaceful transition' if Trump loses, Live: Biden moves closer to reaching 270 votes, Pennsylvania AG on Trump lawsuit: 'We'll win again', Union members picked Biden after Trump 'abandoned' them, Black men drifted from Dems to Trump in record numbers, Fox News hosts question network's Ariz. call for Biden, Trump campaign unleashes wave of suits in key states, Coach cracks down on Tate's 'selfish behavior', Giants trainer may have saved this player's wife's life, California's Prop. But that isn't stable - this is much like "carbonic acid", H₂CO₃, which is present in only low concentration when you add acid to bicarbonate, HCO₃⁻ – it is mostly present as CO₂.
