Question 21 (5 points) Which of the following is true for the conjugate base of a strong acid? The conjugate base of a strong acid acts as a weak acid. As the strength of the acid increases, the strength of the conjugate base decreases. The conjugate base of a strong acid is a strong base. As the strength of the acid increases, the strength of the conjugate base also increases. Question 22 (5 points) The Ksp...

help with 5 and 6 please
5. Choose the effective pH range of a HF/Naf buffer. For HF, Ka = 3.5 x 10-4 6. If a small amount of a strong acid is added to buffer made up of a weak acid, HA, and the sodium salt of its conjugate base, NaA, the pH of the buffer solution does not change appreciably because a) the Ka of HA is changed. b) the strong acid reacts with Ato give HA, which...
