pH Flashcards
1
Q
how to determine the pH of a STRONG acid from a given concentration
A
take the -log of the concentration
2
Q
how to determine the pH of a STRONG base from a given concentration
A
find pOH: -log of concentration
pH = 14-pOH
3
Q
strong acids
A
HCL
HBr
HI
HNO3
H2SO4
HClO4
4
Q
strong bases
A
LiOH
NaOH
KOH
Ca(OH)2
Sr(OH)2
Ba(OH)2
5
Q
how much [OH-] and [H+] are in water
A
1.0x10^-7 each
water is about pH 7, so 7 each
6
Q
how do you calculate [H+] from a given pH
A
[H+] = 10^-pH
7
Q
[OH-] =
A
[OH-] = 10^(14-pH)
8
Q
1 pH unit is a _____ fold difference
A
10
