How does the hydrogen carbonate ion react with a strong acid?

• It remains unchanged.

• It forms a salt.

• It accepts a proton to form carbonic acid.

• It donates a proton to form carbonic acid.

What is the result when the hydrogen carbonate ion reacts with a base?

• It remains unchanged.

• It forms water and a carbonate ion.

• It forms a salt.

• It forms carbonic acid.

What is the old-fashioned name for the hydrogen carbonate ion?

• Phosphate

• Bicarbonate

• Carbonate

• Sulfate

What does the term 'amphiprotic' refer to?

• A substance that can act as both an acid and a base.

• A substance that can only act as an acid.

• A substance that can only act as a base.
