CsF is a basic salt I understand the process and why it is. I just memorized that HF is a weak acid. But can someone actually explain why HF is a weak acid? I hate memorizing... Understanding is way easier

Conjugate base of HF is F- which is most electronegative...thus being most stable. Since the conjugate base is most stable, the acid is weaker..
