On top of that we have a conjugate acid and a conjugate base.

除此之外，我们有共轭酸和共轭碱。

A conjugate acid and base are two different molecules that are almost identical except for one hydrogen atom.

共轭酸和碱是两个不同的分子，除了一个氢原子外几乎完全相同。

The same can be said for strong bases and their weak conjugate acids.

强碱及其弱共轭酸也是如此。

For every acid, there is a conjugate base and for every base there is a conjugate acid.

每一种酸都有一个共轭碱， 每一种碱都有一个共轭酸。

If a base comes in the conjugate acid is gonna eat that part up and again lock the pH at 7.4 That pH of 7.4.

如果碱进入，共轭酸会吃掉那部分，将 pH 值锁定在 7.4。pH 值 7.4。

A buffer solution is a mixture of a weak acid plus its conjugate base, or a weak base plus it's conjugate acid.

缓冲溶液是弱酸加上它的共轭碱， 或弱碱加上它的共轭酸的混合物。
