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. And so that's why it is a non polar molecule. Now, because carbon dioxide is non polar and because our blood plasma consists mostly of water, a polar molecule, that implies that carbon dioxide will not actually dissolve in our blood plasma very easily. So how exactly do we solve this problem?
