Question

**Chemistry 12 Question**

Consider the following example:
HF is a weak base (WB)

HF + H2O <--> F- + OH-

Does increase in OH- ions mean increase in concentration of OH- ? If yes, does increase in OH- concentration means the stronger the weak base becomes?

I believe no to the last question:
POH= - log([OH-])
Pkw= POH + PH
PH= Pkw - POH , so the higher POH, the lower PH which means more acidic the substance (HF) and less basic it becomes.

Am I right? Please explain and clarify it for me further. Thank you.
