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?
What are the Five types of chromatography by stationary phase?
Molecular Exclusion
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.
