Question | Answer |
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) |
