Just to check with all of you: usually from left to right equations. : Acid + Base <=> Conjugate Base + Conjugate Acid In that order? Does it matter which state its in - will that change the order? cos I came across a question with answers which does this: H2CO3(aq) + H2O(l) <=> HCO3- (aq) +...

There are many slight variations of these definitions... amphoteric (oxide): an oxide that exhibits BOTH acidic and basic qualities. but other definitions go on to say it can act EITHER as an acid or a base... eg. water can act as an acid OR a base within a chemical reaction. Therefore it is...
