- That carbon dioxide can diffuse into a cell and react with water to form carbonic acid, which quickly breaks into a proton and bicarbonate.
或者，磷酸鹽濃度也會因為攝取過量，以及透過腸胃道或靜脈輸液進入血液，而快速升高。
- Another situation is when living cells get affected by respiratory acidosis, which is when the carbon dioxide levels rise because a person isn't breathing or ventilating it out of the lungs quickly enough that carbon dioxide can diffuse into a cell and react with water to form carbonic acid, which quickly breaks into a proton and bicarbonate.
另外一種情況是，當活細胞受到呼吸性酸中毒影響時，這表示二氧化碳水準升高，因為人體無法足夠快地將二氧化碳排出肺部，二氧化碳會擴散到細胞內並與水反應形成碳酸，碳酸會迅速分解成質子和碳酸氫根。

- And when that CO2 dissolves in water, it creates carbonic acid.
而當二氧化碳在水中溶解時，會製造碳酸。
- These are both things the carbonic acid in bubbly water gets blamed for.
這兩件事都是氣泡水中碳酸被歸咎的事情。

- but it's just the way the chemistry plays out: dissolved CO2 molecules combine with water to form what's called carbonic acid, which in turn combines with carbonate to form hydrogen carbonate.
但這只是化學作用的結果：溶解的 CO2 分子與水結合形成所謂的碳酸，碳酸又與碳酸鹽結合形成碳酸氫鹽。
- molecules combine with water to form what's called carbonic acid, which in turn combines

- CO2 is [a molecule] that dissolves in water and becomes carbonic acid
二氧化碳是一種酸... 若溶解在水中會變成碳酸
水會過期嗎？ (Does Water Ever Expire?)
- By being exposed to air, the water absorbs some CO2, and a tiny portion of that, about 0.13%, is converted into carbonic acid.
水暴露在空氣中時，會吸收一些二氧化碳，而其中的一小部分，大約 0.13%，會轉變為碳酸。
- Some carbonic acid will then lose a proton or two, forming bicarbonate or carbonate respectively.
部分碳酸會解離出一到兩個質子，分別形成重碳酸鹽或碳酸鹽。
