Chapter 10 - Acids And Bases Flashcards
1
Q
What kind of acid has a negative pka?
A
A strong acid
2
Q
What is the log trick?
A
Do some practice until it is cement:
[anything] = m x 10^-n
Then, p (anything) = n-1.(10-m)
Ex: -log (2.1x10^-8)
7.79
3
Q
How do you go from p(OH) to a OH concentration?
A
Reverse log trick
POH = 13.3
[OH] = 7 x 10^-14
4
Q
What is gram-equivalent weight?
A
g/eq = g/mol x mol/eq
Mol/eq for h2so4 would be
1/2
Naoh would be 1/1
5
Q
Henderson hassle fuck equation
A
Ph = pka + A/Ha
