What is Forchhammer's principle? Give examples of the evidence which allowed Georg Forchhammer
to develop this principle. How do residence times provide a foundation for this principl What will be an ideal response?
ANS:Answer
should include:
? The Forchhammer principle is known as the principle of constant proportions. Georg
Forchhammer realized that the ratio of major dissolved solids were constant in various
samples of seawater.
? There is approximately 55.05% of chloride ions found in high and low salinity waters.
He looked at samples from the Northern Atlantic and the Arctic Ocean to measure these
ratios.
? William Ditmar was able to provide more evidence for this principle as he analyzed
samples taken in the HMS Challenger.
? Constituents that have residence times longer than it takes for the ocean to mix assures a
thorough mixing. They become evenly distributed throughout the ocean.
