Blood is buffered by carbonic acid and the bicarbonate ion. Normal blood plasma is 0.024 M in HCO3 and 0.0012 M in H₂CO3. (pK₂1 for H₂CO3 at body temperature is 6.1.) If the volume of blood in a normal adult is 5.2 L, what mass of HCI could be neutralized by the buffering system in blood before the pH fell below 7.0 (which would result in death)? Express your answer to two significant figures. MHCI Given the volume from Part B, what mass of NaOH could be neutralized before the pH rose above 7.7? Express your answer to two significant figures. mNaOH VO ΑΣΦ Submit V ΑΣΦ Previous Answers Request Answer ? ? 8
