Acid-base Equilibrium Flashcards
1
Q
pH of acids
A
Less than 7
2
Q
pH of bases
A
Greater than 7
3
Q
pH of pure water at 25 degrees Celsius
A
Only 7
4
Q
Who donates and who accepts H+
A
Acids donate and bases accept
5
Q
What is the hydronium ion
A
H3O+
6
Q
What is H+
A
A proton
7
Q
Strong acids
A
HNO3, H2SO4, HClO4, and HBr
8
Q
Strong bases
A
Group 1 and 2 hydroxides (whatever dissolves in group 2 hydroxides completely ionize)
9
Q
pH
A
-log[H+]
10
Q
[H+]
A
10^-pH
11
Q
The stronger the acid
A
The weaker its conjugate base.
12
Q
Acid-base reactions favor the direction of the strong side
A
If K>1, then the reactants are stronger
13
Q
[H+] =
A
Square root MaKa, only use if x is really small compared to Ma and don’t use if pH is given to you
14
Q
“X” in the ice box calculation is…
A
[H+] = weak acid
[OH-] = weak base
15
Q
% ionization of a weak acid
A
[H+]/Ma
