Question
Can gases move through the atmosphere and have an effect on water quality far from the pollutant source? Do you think that the reactions in your polluted world are creating gases that have an impact on the pH of lakes in your polluted worlds? Write a summary paragraph presenting evidence supporting your answer to this question. For lakes of the same size at different distance, what kind of effect did the distance of the lakes from the pollutant source have on the change seen in the quality of water? What sort of difference did distance have on the time it took to see a change? For lakes of different size at the same distance from the source, what kind of effect did the size of the lakes have on the change seen? What sort of difference did lake size have on the time it took to see a change?Explanation / Answer
Q1
Most likely, since gases will become more soluble, since their partial pressure increases, meaning they will be more soluble in water (lakes)
This is according to phase equilibrium, for an increase in partial pressure of gas, expect an increase in solubility of gas in liquid phase.
Q2
Clearly, the more distance the lake form the pollution point is, the least polluted it will be
This is once again due to the partial pressure of gases, the partial pressure is directly propoertional to the concentration of pollutant in gas
Expect far lakes to have LESS pollution
Q3.
No effect, since we talk about concentrations. If you talk about absolute contamination
