A patient is brought into the emergency department in a disorientated state. You smell ketones on his breath and suspect he may be in diabetic ketoacidosis. From lab results you find that his blood [HCO3- ] = 12 mM, and his [CO₂] = 1.8 mM. What would you expect his blood pH to be? (pK for [HCO3-]/[CO₂]) = 6.1).
