I have been coming across some questions which asks to identify whether the given salt is acidic, basic or neutral. I solve them like this:- For example the salt is NaCl, the answer is neutral as NaOH and HCl are strong base and strong acid respectively. But for problems like KF:- I was confused on this one. I thought that KOH is a strong base and about HF i didn't know anything about it. I was not able to think whether HF is strong or weak acid. Is there any way to find whether the given acid or base is strong or weak? Thanks!
