Question

7. Our next question will be asking about the weak acid hydrofluoric acid (HF). a) Provide the acid ionization equation for HF (reaction with water). Be sure to provide the proper phases for all species within the reaction. b) Provide the expression for the Keq for this reaction, called the acid dissociation constant Ka. c) Given that the Ka of HF is 6.3 x 10-4, determine the pH of a 0.500 M solution of HF. You’ll find the use of an ICE table helpful. d) As discussed in class, the presence of H+ in solution impacts the dissociation of acids. What is the equilibrium concentration of F- if the 0.500 M HF solution contains 0.01 M H3O+? e) What is the percent ionization of the HF in the solution in (d)?

a) Provide the acid ionization equation for HF (reaction with water). Be sure to provide the proper
phases for all species within the reaction.
b) Provide the expression for the Keq for this reaction, called the acid dissociation constant Ka.
c) Given that the Ka of HF is 6.3 x 10-4, determine the pH of a 0.500 M solution of HF. You’ll find

d) As discussed in class, the presence of H+ in solution impacts the dissociation of acids. What is
the equilibrium concentration of F- if the 0.500 M HF solution contains 0.01 M H3O+?
e) What is the percent ionization of the HF in the solution in (d)?
