ECB Project assignment: Data & questions
For the ECB project, you are required to use Visual MINTEQ freeware for aqueous speciation.
For the project use the following concentration of species:
Ionic strength= 0.05 M
Fe(III) = 20 ppm
Fe(II) = 20 ppm
Cd(IV) = 15 ppm
Hg = 5 ppm
Cr(IV) = 10 ppm
As(IV) = 10 ppm
Carbonate = 25 ppm
Bicarbonate = 15 ppm
Sulfate = 12 ppm
silicate = 15 ppm
chloride = 35ppm
For your specific heavy metal:
1) List the major species (of your specific metal) at each pH level (pH =1 to 14). Major species is defined as something with >10% concentration.
2) Draw the pC-pH diagram of your particular species.

RET: Assignment#4
Due Date: Oct 25, 2017
For your own home, compute the AC and DC load requirements and design a) stand-alone and (b) grid-connected PV array along with all the appurtenant devices. You may use the same specifications for the devices as used in the class examples.

M Tech: Env: ECB Assignment# 4
Assignment# 4
Deadline: Sep 29, 2017
For the Fe(III) in water problem discussed in the Complexation slides, assume a 10^-9 M Fe(III) aqueous solution. Draw the pC-pH diagram for all the Fe species in the solution.
Online submissions are preferred for the calculation and pC-pH plots.
You may submit the chemical equations and mathematical simplification parts in hard copy.
