lol.. I always get confused with those... Amphiprotic: The ability to behave as either Bronsted L acid or bronsted l base examples: water, Hydrogen carbonate ion so in other words an amphiprtoic subtance can act either as a proton donor or proton acceptor Amphoteric: Oxides that react with acids to form salts, but which also react with alkalis ...Amphoteric oxides can be neutralised by either an acid or a base examples: Al2O3, ZnO, PbO, SnO and As2O3 Last edited by physician; 12 Jul 2005 at 10:17 PM. | |

21 Jun 2006, 12:36 PM | Amphoteric substances are a sub-category of amphiprotic substances. An amphoteric substance can act as a base or an acid, while an amphiprotic substance can donate or accept a proton, be it an acid-base reaction or not.

Don't believe it! If they were the same thing... why are there two different terms? Why are there two different terms? (which are confusingly similar)

7 Sep 2009, 4:42 PM  | simple explanation: Amphiprotic means the ability of a substance to act as both an acid ad a base in solution. Amphoteric oxides are those which react with acids to form salts but also react with alkalis.

Specifically, amphiprotic substances can donate OR accept protons (H+), but not necessarily in an acid/base reaction. ANYWAY, as "amphoteric" is not in the syllabus...

7 Sep 2009, 4:42 PM | even if its not in the syllabus, or even if we don't notice it in the syllabus, it is STILL tested in the hsc, ive seen it in past papers (after the syllabus was amended in 2002(?))
