WebbThe Arrhenius theory, which is the simplest and least general description of acids and bases, includes acids such as HClO 4 and HBr and bases such as NaOH or Mg(OH)2. For example the complete dissociation of HBr gas into water results generates free H3O + ions. HBr ( g) + H2O ( l) → H3O + ( aq) + Br − ( aq)

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).
