WebbThe normal PaCO2 level is 35-45 mmHg. CO2 forms an acid in the blood that is regulated by the lungs by changing the rate or depth of respirations. As the respiratory rate increases or becomes deeper, additional CO2 is removed causing decreased acid (H+) levels in the blood and increased pH (so the blood becomes more alkaline). WebbZenu Destroyer of Worlds (AK) bleach is basically a solution of sodium HypoChlorite, or NaClO. This is a salt that contains the anion of the weak acid HClO, hypochlorous acid, and the cation of the strong base, NaOH. Because NaOH is a strong base, it fully dissociates into Na+ ions and OH- ions.
