[OH-] & pOH

Postby Labiba Sardar 2A » Sat Dec 07, 2019 11:38 am

Can someone please explain conceptually why decreasing [OH-] makes the pOH increase?

The p in p[OH-] stands for -log base 10. You can look at a graph of y=p(x). When the inputted value increases, the function decreases. Likewise the value of When the concentration of OH- decreases, the function p[OH-] increases. This is true for [H+] as well.

Yeah, think of pOH is for OH just as pH is for H. Its just that pH is used more often.

pH or pOH is the negative log of the concentration of the molecule, which means that they have an inverse relationship.
