What are the 3 factors in the Debye-Huckel Equation
|
U- Ionic strength
Z- Charge Alpha- Atomic Radius |
|
|
How are the three facors in the debye-huckel equation related to the activity coefficient?
|
U increases, AC decreaces
Z increases, AC decreases Alpha increases, AC increases |
|
|
What is it called when a ligand bonds to a metal in multiple places?
|
Chelating Effect
|
|
|
What is a ligand that can bond to a metal in multiple places called?
|
Multidentate Ligand
|
|
|
What are three standard reference electrodes?
|
Standard Hydrogen Electrode
Saturated Ag/AgCl electrode Saturated Calomel Electrode |
|
|
What three things must an indicator electrode do?
|
Respond Quickly
Be selective Be reproducible |
|
|
What are the two general types of indicator electrodes?
|
Metal Electrodes
Membranne Ion Selective Electrodes |
|
|
What are the three sources of peak broadening
|
A- Multiple paths
B- Longitudinal Diffusion C- Mass Transfer |
|
|
What are the two types of chromatography by mobile phases?
|
Gas
Liquid |
|
|
What are the Five types of chromatography by stationary phase?
|
Adsorption
Ion-Exchange Partition Molecular Exclusion Affinity |
|
|
Describe Adsorption Chromatography
|
solute is carried by gas or liquid and is adsorbed on the surface of the solid stationary phase
|
|
|
Describe Ion Exchange Chromatography
|
ions are covalently attached to solid stationary phase, they attract oppositely charged analyte in the liquid mobile phase
|
|
|
Describe Partition Chromatography
|
Liquid is on the walls of the column as the stationary phase, and the analyte in the gas mobile phase equilibrates bt/ the gas and liquid
|
|
|
Molecular Exclusion
|
Separation by size, the gel stationary phase catches small particles and allows large ones through
|
|
|
Describe Affinity Chromatography
|
Molecules are covalently bonded to stationary phase, they only bond with a specific molecule in the mobile phase, these molecules can be dislodged when all of the other mobile phase is eluted.
