Carbonic acid is actually very unstable ...

碳酸实际上是不稳定的。

When water absorbs carbon dioxide, it produces carbonic acid.

当水吸收二氧化碳时会产生碳酸。

But the truth is, that is not carbonation or carbonic acid's fault.

但事实是，那并非碳酸化或是碳酸的错。

And finally the ocean. It is absorbing carbon dioxide as carbonic acid. And it's rapidly changing the Ph worldwide.

最后是海洋。它吸收着二氧化碳的碳酸。因此造成世界范围内的Ph值的快速变化。

Vast seaweed farms will absorb megatons of carbonic acid, reducing ocean acidity to feed the world with environmentally restorative food.

巨大的海藻养殖场将吸收数百万吨的碳酸，降低海洋酸度，为世界提供环境修复性食物。

This is due to the fact that the yeast produces a kind of gas, called carbonic acid gas, inside the dough.

这是因为酵母在面团内部生成了一种名叫碳酸气的气体。

Since your blood is mostly water, when CO2 dissolves in it, it forms carbonic acid, which breaks down into bicarbonate and hydrogen ions.

由于你的血液主要是水，当二氧化碳溶解在其中时，它会形成碳酸，分解成碳酸氢盐和氢离子。

This is an equilibrium reaction, where it can form carbonic acid.

这是一个平衡反应，它可以形成碳酸。

That carbon dioxide can diffuse into a cell and react with water to form carbonic acid which quickly breaks into a proton and bicarbonate.

二氧化碳可以扩散到细胞中，与水反应形成碳酸，它会迅速分解成H+和HCO3-。

Carbonic acid is involved in the oceans taking up carbon dioxide from the atmosphere.

碳酸参与海洋从大气中吸收二氧化碳。

As long as protons are available, the bicarbonate ions can grab a second proton to become uncharged carbonic acid.

只要质子可用， 碳酸氢根离子就可以抓住第二个质子， 变成不带电的碳酸。

Carbon dioxide is carried in several ways, but is mostly converted to an acid called carbonic acid.

二氧化碳以多种方式携带，但主要转化为称为碳酸的酸。

Carbonic acid is incredibly important in how your body deals with excess carbon dioxide in its bloodstream.

碳酸在您的身体如何处理血液中过量的二氧化碳方面非常重要。

During heavy rains water, molecules in the rainwater react with the carbon dioxide in the atmosphere to form carbonic acid, which makes the rainwater slightly acidic.

在大雨期间，雨水中的分子与大气中的二氧化碳发生反应，形成碳酸，使雨水呈微酸性。

Carbonic acid, for instance, which is basically just carbon dioxide dissolved in water, dissociates to form carbonate ions and hydrogen ions.

例如，碳酸基本上只是溶解在水中的二氧化碳，会分解形成碳酸根离子和氢离子。

The water molecules and carbon dioxide molecules can then react to each other, to form carbonic acid, which lowers the pH of the water, making it slightly acidic.

之后，水分子与二氧化碳分子得以相互作用，形成碳酸。而碳酸会降低水中的 pH 值，让水变得更酸一点。

Carbonic acid in particular is formed when CO2 is dissolved in water, meaning that it is present in increased concentrations in our seas due to CO2 in the atmosphere.

特别是碳酸，当二氧化碳溶解在水中时就会形成碳酸，这意味着由于大气中的二氧化碳，我们海洋中的碳酸浓度会增加。

Once it’s in the ocean, carbon dioxide reacts with water molecules to form carbonic acid, which breaks up into carbonate ions and hydrogen ions.

一旦进入海洋，二氧化碳就会与水分子反应形成碳酸， 碳酸分解成碳酸根离子和氢离子。

No matter how it gets there, carbon dioxide reacts with water to form carbonic acid; a weak acid that dissociates into hydrogen and bicarbonate ions.

无论它如何到达那里， 二氧化碳都会与水反应形成碳酸；一种离解成氢离子和碳酸氢根离子的弱酸。

So when you start to exhale CO2 faster than your cells release it, its concentration in your blood drops. And with less carbonic acid around, your blood's pH starts to rise.

因此，当你呼出二氧化碳的速度超过细胞释放二氧化碳的速度时，二氧化碳在血液中的浓度就会下降。周围碳酸的减少，你血液的 pH 值开始上升。
