Q: Carbonic acid can dissociate into hydrogen carbonate ions and what?


Read this paragraph and choose the correct option from the provided answers:

Carbon dioxide is slightly soluble in water. There is an equilibrium reaction that occurs as the carbon dioxide reacts with the water to form carbonic acid (H2CO3). Since carbonic acid is a weak acid, it can dissociate into protons (H+) and hydrogen carbonate ions (HCO 3 −).

 Choices:

- protons

- atoms

- electrons

- protons


A:
protons
