acid base equalibria Flashcards
1
Q
what is a A Bronsted-Lowry acid?
A
= donate a proton
2
Q
A Bronsted-Lowry base?
A
= accept a proton
3
Q
How do we calculate PH?
A
= PH= -log[H+]
= concentration of hydrogen ions in solution
4
Q
what is a strong acid?
A
= strong acids completly dissociate
5
Q
how do we find [H]+, concentration of hydrogen ion fron PH?
A
= 1 x 10^-PH
6
Q
what equalibrian does water follow?
A
= H2o => H+ + OH-
7
Q
What is the equation for kw?
A
= Kw= [H+][OH-]
8
Q
What is the value for kw at 25 degrees?
A
= 1x10^-14
9
Q
How do we find the PH for pure water?
A
= neutral solutions [OH-] = [H+]
= kw= [H+]^2
= [H+]= swuare root of kw
10
Q
Why does water not appear in the equation?
A
= it is (almost) constant
11
Q
What is an weak acid?
A
= slightly dissociate in wtaer
12
Q
the larger the ka the what?
A
= the stronger the acid
13
Q
