Salinity
the total amount of dissolved salt in an aqueous solution
mass %
(g solute/g solution) x 100
Parts Per Thousand (ppt)
(g solute/kg solution)
Parts Per Million (ppm)
(mg solute/kg solution)
Molarity
(moles solute/L solution)
%Transmittance
%T = (I/Io)x 100
Absorbance
A = - log(%T/100)
Beer’s Law
A = ebc
(e molar absorptivity)
(e molar absorptivity)
molar absorptivity
is the slope of the calibration curve trendline
m in y=mx+b
m in y=mx+b
Beer’s Law states that absorbance and concentration are...
directly proportional
What is the differential rate expression for delta[C] with time?
d[C]/dt = k2[B]
What is the differential rate expression for delta[B]with time?
d[B]/dt = k1[A]-k2[B]
Rate constants can be determined experimentally by....
fitting concentration versus time data with rate laws
Paper chromatography can be used to...
separate mixtures such as transition metal solutions into their constituents
Transition metal complexes involve...
electrons based in the five 3d orbitals of the metal ion in the complex
This split of orbitals introduces an energy gap between...
the lower energy orbitals and the higher energy orbitals
Colligative Propertie
physical properties that depend on the number of solute particles in solution
Freezing Point Depression
The freezing point of a pure solvent is higher than that of a solution. More concentrated solutions have lower freezing points.
The magnitude of freezing point depression is directly proportional to the concentration of solute
Higher solute concentration = larger freezing point depression = lower the freezing temperature
A buffer works best within...
±1 pH of the pKa of the acid involved
pH
pKa+log(base/acid)
Oxidation
the loss of electrons (charge becomes more positive)
Reduction
the gain of electrons (charge becomes more negative)
Reducing Agent
the species being oxidized
Oxidizing Agent
the species being reduced
Ecell=
Ecathode-Eanode
Positive Ecell
indicates a cell capable of doing work
Negative Ecell
indicates that energy must be supplied for the cell to function
Anodic half cell
compartment where oxidation occurs
Cathodic half cell
compartment where reduction occurs
Bentonite
can be considered a nanomaterial, with layers that can be used to trap molecules,such as polycyclic aromatic hydrocarbons, and take them out of water sources
PAHs
are formed from incomplete combustion of organic materials
