CHMB41H3 Lecture Notes - Lecture 5: Bond Length, Weak Base, Electron Affinity
Document Summary
The lower value of pka the stronger the acid. Compounds such as amines have very high pka so they are not acidic they are basic, they have lone pairs. We don"t need to memorize exact values but we need to know ~ range. This time you need to figure out whats on the right side of the equation. The question is can you neutralize ant bites with ammonia which is nh3. Q: can you if you have formic acid on your skin add ammonia and neutralize it. A: yes you can neutralize ant bite by using ammonia. Unfortunately we wont be given pka of acid all time to find equilibrium direction but rather you will have to base your decision on other factors that you can compare on other molecules to identify them as acids. What we have to look at is the acidity of their conjugate base!
