Q
What is pH
A
A bulk property
-of a solution
concentration of H+
pH = -log10c
12
Q
What is pKa
A
A molecular property
The acidity of a proton in a molecule
a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero.
13
Q
High pKa =?
A
the weaker the acid and the lower its ability to donate its protons.
14
Q
Low pKa
A
the stronger the acid and the greater its ability to donate its protons.
15
Q
pKa relation to Ka
A
the negative log base ten of the Ka value
Ka= acid dissociated constant
pKa =-log10[Ka]
