A 10.00 mL aliquot of a solution of a weak acid
, HA, whose pK
a
is 4.76 is titrated
with OH
-
generated by electrolysis of water according to th
e following scheme:
2 H
2
O + 2 e
-
⇔
2 OH
-
+ H
2
(a)
[5 points] If the end point in the titration is ob
served after the passage of a
current of 0.0500 amperes for 2 minutes, what is th
e concentration of HA in the
original sample?
