Topic 12 - Acid-Base Equilibria Flashcards
1
Q
Define pH
A
pH=-log10[H+] or pH=log10(1/[H+])
2
Q
Define a Bronsted-Lowry acid
A
A proton donor
3
Q
Define a Bronsted-Lowry base
A
A proton acceptor
4
Q
Define a conjugate acid-base pair
A
Either a base and the species it forms (its conjugate acid) or an acid and the species it forms (its conjugate base)
5
Q
How can you calculate [H+] from pH?
A
10^-pH
6
Q
How can you calculate Ka of a weak acid HA:
aHA bA- + cH+?
A
Ka= [A-]^b[H+]^c/
[HA]^a
7
Q
How can you calculate the pH of a strong acid HA?
A
pH=-log10[HA]
