Ch 16 Salts Equilibrium Flashcards
1
Q
Anions
A
A- + H2O = HA + OH-
2
Q
What if
Both cation is a weak acid and anions are CB of a weak acid
The anion is amphoteric
A
Determine which is stronger Ka or Kb
3
Q
Polyprotic acids
A
Have to ice table as many times as there are H
Carry concentrations over to next Ice table
4
Q
Relativity of Oxyacids
A
As electronegativity Increases, Ka increases more acidic
More oxygen a more acidic
5
Q
Common ion effect
A
Take the ion that is in the compound asked and take that units as in ice table. Solve for s. Make sure of the squares etc.
6
Q
Will ph effect solubility
A
Break compound into ions. Look at the conjugate acid or base pair. If weak then will effect. If strong then no.
7
Q
Q>Ksp
A
Precipice will form
Q is initial solution molarity
8
Q
Cations
A
Nh4+
