Bood is slightly alkaline, with a pH value ranged from 7.35 to 7.45.

CO2 溶於血裡會產生碳酸 H2CO3,H2CO3 會消耗血液中的酸。但血液中亦有 HCO3^- 離子,HCO3^- 離子是微鹼性的(很多人以為它是酸性的,其實不然),能中和過多的酸。

得純水係中性嫁炸
血係微鹼 ph大約 7.34 - 7.45

我其實唔confirm 血係pH 幾, 但plasma 會transpost CO2 in form of H+ and HCO3-(carbonic acid), so I think blood is acidic
