Write an equation showing the bicarbonate ion acting as an acid.
HCO3^- ==> H^+ CO3^2-
To answer this question, we need to know the chemical formula for the bicarbonate ion, which is HCO3-.
When the bicarbonate ion acts as an acid, it donates a proton (H+) to another molecule or ion. So, the equation for the bicarbonate ion acting as an acid can be represented as:
HCO3- + H2O -> H2CO3 + OH-
In this equation, the bicarbonate ion (HCO3-) donates a proton (H+) to a water molecule (H2O) to form carbonic acid (H2CO3) and hydroxide ion (OH-).
