AP CHEMISTRY QUESTIONS AND ANSWERS FOR EXAM
PREP AND REVISION. 2024/2025 UPDATE
1. binary acids: - contain hydrogen and 1 other element
- start with hydro and end with ic
2. oxyacids: - contain oxygen, hydrogen, and a third element
- the more oxygen, the stronger the oxyacid
3. ending for an oxyacid with high oxygen: ic
4. ending for an oxyacid with low oxygen: ous
5. 2 examples of binary acids: HF, HBr
6.2 examples of oxyacids: H2S04, H2S03
7. strong acids & bases completely in a
solution: ionize, polar
8. polyprotic acids: can donate more than 1 hydrogen ion
9. hydroxyl group vs. hydroxide ion: - hydroxide attaches to a metal,
forms a base hydroxyl group attaches to a nonmetal, forms an acid
10.best and broadest definition: g.n. lewis
1 1 . arrhenius acid: any substance that produces hydrogen or
hydronium ions in a solution
12. bronsted-lowry acid: an acid is a proton donor
13. g.n. lewis acid: an acid is an electron pair acceptor
14. amphoteric: any substance that can act as an acid or base
15. TRUE or FALSE: if a compound has OH-, it's a base:
false: it must have OH attached to a metal
16. another name for a base: metal hydroxide
17. TRUE or FALSE: NaOH is a base: true: OH is attached to a metal
18. TRUE or FALSE: CH30H is a base: false: OH is not attached to a
metal 19. how to make conjugate acid/base pairs: if you have an acid,
remove a hydrogen and make it more negative
20. conjugate base: produced when a bronsted acid donates a proton
21 . conjugate acid: produced when a bronsted base accepts a proton
