How is the toxicity of metal ions to finfish affected by changes in pH? Why?
Homework Answers
In general, free metal ions will increase in lower pH, while more alkaline pH will result in fewer toxic free-metal ions by leading to the formation of carbonate complexes with them. Environmental pH can also impact toxicity through proton competition, where free protons compete with metals for binding sites on the biotic ligand or other complexing ligands such as dissolved organic carbon (DOC).

2nd part only the pH is correct.
Metal ions in aqueous solutions are solvated, or hydrated, by water molecules. Typically this primary hydration sphere is composed of six water molecules. The hydrated metal ion acts as a weak acid, undergoing a stepwise hydrolysis in which it donates an Htion from its water ligands to the surrounding free water molecules. Shown is the hydrolysis of Al(H,0) (pKA = 4.85) in water. Al(H,0)(aq) + H20(1) - 1,0+ (aq) + Al( HO), OH...

report “Rabbits and Wolves”Discuss the changes in parameters and how they affected the population growth curves for each organism (be sure to mention particular changes in the graphs and ending populations). Think about how this simulation could apply to the real world. What other factors or variables would have to be included. What if humans were added as a fourth organism, how would they affect this simulation? Also, do you think that a computer model is a useful tool to...
