, One of the buffers that contributes to pH stability of human blood is carbonic acid
(H2CO3). Carbonic acid is a weak acid that dissociates into a bicarbonate ion
(HCO3-) and a hydrogen ion (H+).
Thus, H2CO3<---> HCO3- + H+
If the pH of the blood drops becoming more acidic, one would expect

the HCO3- to act as a base and remove excess H+ with the formation of
H2CO3-.
What results from an unequal sharing of electrons between atoms, such as found in
H2O?
