|---|---|---|---|---|---|
| Acid | more hydrogen ions than hydroxide ions
🗑
|
||||
| Base | more hydroxide ions than hydrogen ions
🗑
|
||||
| pH | the negative log of the hydrogen-ion concentration
0-7 = ACID
7-14 = BASE
pH = -log[H+]
🗑
|
||||
| pOH | the negative log of the hydroxide-ion concentration
0-7 = BASE
7-14 = ACID
pOH = -log[OH-]
🗑
|
||||
| indicator | acids or bases that undergo dissociation at a known pH
🗑
|
||||
| end point | the point at which the indicator changes color
🗑
|
||||
| acid ionization constant | Ka = (products/acid)
🗑
|
||||
| amphoteric | substances that can act as both acids and bases
🗑
|
||||
| base ionization constant | Kb = (products/base)
🗑
|
||||
| Arrhenius model |
🗑
|
||||
| Bronsted-Lowry model | Acid is the proton donor and the base is the proton acceptor
🗑
|
||||
| conjugate acid |
🗑
|
||||
| Neutralization | a base combined with an acid to neutralize an aqueous solution
🗑
|
||||
| weak acid/base | ionize only slightly in an aqueous solution
(acetic acid and ammonia)
🗑
|
||||
| strong acid/base | completely ionized in an aqueous solution
(HCl and NaOH)
🗑
|
||||
| salt | combining OH- and H+ to make water and using whatever is left over to make a salt
🗑
|
||||
| standard solution |
🗑
|
||||
| Properties of acids | 1. sour taste
2. astringent feel on skin
3. turn blue litmus paper red
4. combine with base to form a salt
5. H3O+
🗑
|
||||
| Properties of Bases | 1. taste bitter
2. feel slimy
3. turn red litmus paper blue
4. combine with acid to form a salt
5. OH-
🗑
|
||||
| Identify A/B Pairs | 1. Determine which compounds go together
2. Loses an H+ (acid/con. base)
3. Gains an H+ (base/con. acid)
TIPS
(+) = acid
(-) = base
**acid/base always on left of yield
**conj. A/B always on right of yield
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
