Qsp
________ is the solubility product for a reaction NOT at equilibrium.
2
New cards
Buffers
________ are solutions that can resist changes in pH.
3
New cards
Henderson-Hasselbalch Equation
pH = pKa + log10(A-/HA)*can use moles or M since its a ratio
4
New cards
Strong Acid/Strong Base at EP
pH = 7.00 and is neutral
5
New cards
Weak Acid/Strong Base titration will create a _____
buffer
6
New cards
Strong Base/Strong Acid at EP
pH = 7.00 and is neutral
7
New cards
Weak Base/Strong Acid at EP
pH < 7.00 from effect of the weak conjugate acid
8
New cards
Common Ion Effect
Suppresses ionization of a weak acid/base due to presence of a common ion from a strong electrolyte
9
New cards
An equivalence point is _____
The point in an acid-base titration where the moles of base = moles of acid
10
New cards
If Q < Ksp
No Precipitation (unsaturated)
11
New cards
If Qsp > Ksp
Precipitation forms
12
New cards
If Qsp < Ksp
No Precipitation (saturated)
