58. During the Apоllо 13 missiоn, rising cаrbon dioxide levels in the spаcecrаft threatened the astronauts. Blood pH is normally held at 7.4 by this set of COUPLED equilibria: CO₂(g, air) ⇌ CO₂(g, blood)CO₂(g, blood) + H₂O ⇌ H₂CO₃(aq)H₂CO₃(aq) + H₂O ⇌ H₃O⁺(aq) + HCO₃⁻(aq) If the CO₂(g) level in the air supply increased, how would blood pH be affected?
