Difference Between Teaching Strategies And Teaching Methods Ppt, ample number of questions to practice H2O is amphoteric or neutral? 2012. Which of the following is amphoteric according to Bronsted-Lowry definition? Amphoteric substances are substances which can act as both acids and bases and thus can accept and donate ions. The bicarbonate ion itself is what is amphiprotic, and this is because it can lose the hydrogen it has to become a carbonate ion (CO32u2212), or it can gain a hydrogen to become carbonic acid (H2CO3).
