|---|---|---|---|---|---|
| arrhenius acid and base | acid produce H
Base produce OH
🗑
|
||||
| Lewis acid and base | acid accepts electron
base loses electron
🗑
|
||||
| bronsted acid and base | acid loses proton
base gains proton
🗑
|
||||
| not all ___ acids are bronsted acids | lewis
🗑
|
||||
| pH is measured | -log [H]
🗑
|
||||
| pOH is measured | -log[OH]
🗑
|
||||
| pH+pOH= | 14
🗑
|
||||
| 10^-3 has pH | 3
🗑
|
||||
| n x 10^-m | m-logn
log n is between 0 and 1
🗑
|
||||
| weak acid and base | partially disassociate in aq soln
🗑
|
||||
| Ka formula | [prod]*[prod]/[reactants]
🗑
|
||||
| smaller kb _____ base | weaker
🗑
|
||||
| conj base is ____ than conj acid | stronger
🗑
|
||||
| large ka ________ acid | strong
🗑
|
||||
| amphoteric | acts as either acid or base
🗑
|
||||
| in titration color change depicts | end pt
🗑
|
||||
| equiv pt | acid eqiv = base eqiv
🗑
|
||||
| hh eqn pH= | pKa + log [conj base/ weak acid]
🗑
|
||||
| hh eqn pOH | pHb = log [conj acid/ weak base]
🗑
|
||||
| acids formed from halogens increase | acidity increases down the grp
🗑
|
||||
| the larger the anoion the weaker the bond therefore | stronger acid
🗑
|
||||
| in HX compds y does acidity increase down the grp | go down the grp the X size increases and forma a weaker bond
🗑
|
||||
| strengths of HOX acids increase | up grp HOI<HOBr<HOCl<HOF
🗑
|
||||
| why does HOX acidity increase up a grp | the HO ionizes (gains electron) more readily when bonded to high electroneg atom
🗑
|
||||
| more negative pka | stronger the acid
🗑
|
||||
| more oxygen on HX | greater the acidity
🗑
|
||||
| HX shortest and strongest bond increases | up a grp ( weaker acid)
🗑

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.
