what are the species present in a 1.0M solution hydrofluoric acid? write formulas with state symbol?
Homework Answers
HF dissociates in water giving rise to H+ ion and F- ion. Since it a weak acid, it undergoes little dissociation (very low dissocaition constant, Ka) and hence most of the HF remains in undissociated form.
HF(aq) = H+(aq) + F-(aq)
Initially- 1M 0 0
Change - -(x ) +(x) +(x)
Equilibrium - (1 -x ) x x
(undissociated HF)
