We're being asked to determine the effect of addition of small amount of hydrochloric acid to an ideal buffer at 0.1 M HF
Recall that a buffer is a solution that resists pH change upon the addition of an acid or base.
Buffer neutralizes small amounts of that added acid or base, thus maintaining the pH.
The HF buffer system contains HF and F- ions:
HF (aq) + H2O (l) ⇋ H3O+ (aq) + F- (aq)
What will happen is a small amount of hydrochloric acid is added to a 0.1 M ideal buffer based on HF?
a. The percent ionization of HF will increase.
b. The percent ionization of HF will decrease.
c. No effect in the precent ionization
d. Buffer system will be destroyed
