pH = 5.45
pOH = 8.55
.0023 M HCl
.0018 M KOH
Please help i’m so lost in class, any explanation would be greatly appreciated!

Knowing 2 things, lower pH, stronger acid. Low as in around 1-3 on pH scale, now this is easy.
KOH…in water it becomes K+ and OH-. OH- is a STRONG base, very high pH.
pOH = 14-pH. So pOH = 8.55 means pH = 5.45, same as the other
KOH
5.45, 5.45
HCl is strong acid, it’s going to have a pH near the bottom of the scale.

Just did this, the correct answer is, in the order of most acidic to most basic:
0.0023 M HCl
ph = 5.45
pOH = 8.55
0.0018 M KOH

This guy is right, except the pH=5.45 and the pOH=8.55 are equal to each other so they re placed on top of each other.
