Given the pH of a sol'n is 7.4, what is the H
_{3}
0
^{+}
concentration
10 ^
^{-pH }
(Note
: 7.40 is 2 places past decimal, your answer should be this:
4.0x10
^{-8 ) }
Given the pH of a sol'n is 9.61, what is the -OH concentration
First find the pOH: 14-9.61 = 4.39. Now you can do this: 10 ^
^{(-4.39)}
=
4.1x10
^{-5}
So, from pH to H30+
10^
^{-pH}
A sample of gastric juice has a H
_{3}
0
^{+}
concentration of 0.045. What is the pH
-log (0.045) =
1.35
(since there are 2 sig figs in the concentration, put 2 places past the pH)
Given pK
_{a}
find K
_{a}
-logK
_{a}
Know how to use the Henderson-Hasselbalch equation.
Remember that the [A
^{-}
] is the CB SALT and [HA
^{-}
] is the ACID. "A" for acid and use this acid's pK
_{a}
