One of the buffers that contributes to pH stability in human blood is carbonic acid, H2CO3, which is formed when CO2, the waste product of cellular respiration, reacts with water in blood. Carbonic acid is a weak acid that when placed in an aqueous solution dissociates into a bicarbonate ion (HCO3)and a hydrogen ion (H+). Thus: CO2+H2OH2CO3HCO3+H+ Which of the following will occur if the pH of the blood decreases? Click all that apply. Carbonic acid will dissociate into a bicarbonate ions and hydrogen ions. Bicarbonate ions will join to hydrogen ions, forming carbonic acid. The forward reaction will be favored. The reverse reaction will be favored. You will immediately die
