Now, let's begin by discussing what actually affects the PH of our blood plasma. Well, recall that inside our cells of our tissues, the cells undergo many type of metabolic processes, for example, cellular respiration. And when cells undergo these processes, the major byproduct waste byproduct that is produced is carbon dioxide. Now, carbon dioxide is, of course, non polar. And that's because carbon dioxide consists of two polar bonds that point in opposite directions. And so because the dipole moments cancel out, the carbon dioxide has a net dipole moment of zero.
