It’s super happy fun time (for almost the last time…) Show me what you know about acids and bases, then we can start our end of year review 🙂
Warm Up 101
(1) What does it mean when we say that an acid is strong or weak? What is stronger, a 0.0500 M HCl solution or a 0.200 M HF solution? Justify your response.
(2) The dissociation of formic acid is represented by the chemical equation below.
HCOOH(aq) ⇄ H+(aq) + HCOO–(aq)
(a) Write the equilibrium constant expression for this reaction.
(b) For a 0.200 M HCOOH solution, the pH of the equilibrium mixture is measured at 2.23. What is the [H+] for this solution?
(c) Determine the value of Ka for formic acid.
HW Check (Practice 9.4b)
- Review Topics 5 and 6 over the weekend. Come with questions!
