Explanation & Answer

Thank you for the opportunity to help you with your question!

HF(aq) + H2O(l) <----> H3O(aq) + F(aq)
1. Hydrochloric acid, HF(aq), dissociates in water as represented by the equation above

HF + H2O H3O + F Ka=7.2 X10^-4 1.

Please let me know if you need any clarification. I'm always happy to answer your questions.
