Acid Base Equilibria Flashcards
1
Q
Strong acid strong base pH
A
3-10 range
2
Q
Weak acid strong base pH range
A
6.5-11
3
Q
Weak base strong acid range
A
3-7.5
4
Q
Strong acid
A
pH = - log [H+]
[H+] = 10-pH
5
Q
Weak acid pH
A
pH= ✓Ka x [acid]
6
Q
Ka equation
A
Ka = [H+]2 / [acid]
7
Q
pKa equation
A
pKa = - log Ka
8
Q
Strong base Kw
A
Kw = [H+] [OH-] = 1x10-14
9
Q
Strong base pH
A
pH = 14 - ( - log [base] )
10
Q
[H+]
A
[H+] = 10−pH
11
Q
pH
A
pH = −log [H+]
12
Q
What does high Kc value suggest
A
More dissociation
So stronger acid
13
Q
How to find new conc when diluting an acid
A
New conc = (old conc x old vol) / new volume
