Chapter 16: Acid-Base Equilibria Flashcards
1
Q
What do “weak” acids mean?
A
That their reactions with water do not go to completion.
2
Q
For a weak acid solution, how is the amount of the ionization measured?
A
Acid-ionization constant (the equilibrium constant for the ionization of a weak acid)
3
Q
What is the degree of ionization?
A
The fraction of molecules that react with water to give ions.
4
Q
What is the general rule regarding polyprotic acids ionizaition?
A
The second ionization constant Ka2, of a polyprotic acid is much smaller than the first ionization constatn, Ka1.
5
Q
What is hydrolysis?
A
The reaction of an ion with water to produce the conjugate acid and hyroxide ion or the conjugate base and hydronium ion.
