And also, what about pH's alter ego pOH?

可，pH什么？

The pOH in this case is 10.5.

另一方面，比如说氨这种弱碱。

And finally, you learned about some cool mathematical connections between pH and pOH.

弱酸比如柠檬酸，电离完全。

Just as we can calculate the pH of a substance from it's hydrogen ion concentration, we can calculate the pOH.

就一种在同pH值环境中会显现同颜色的化物质。

But, if the poor creature has lost so much skin from off her back. Poh, poh! That is just one of Tim's large stories.

但，如果可怜的家伙背上脱了很多皮。咳，咳！那只蒂姆编的一个故事。
