An aqueous solution of carbonic acid (H2CO3) contains H2CO3, HCO3–, and CO32– in different concentrations. Identify the amphoteric species in the solution. Ignore the water present in the solution.
The ion hydrogen oxalate (HC2O4–) is amphiprotic species. Provide the chemical equations illustrating how the hydrogen oxalate ion reacts with water as an acid and base.
Write equations that show the amphoteric species, NH3 and HSO4-, acting as both an acid and a base.
All of the following is amphoteric except
Both H2O and H2PO4- are amphoteric. Write an equation to show how each substance can act as an acid and another equation to show how each can act as a base.
