Good morning,
The first day we can
watch that the water volumen has decreased a Little. There is an half an inch
till the sedimentation starts.
In the parts of the
bottle which is influenced by the light, if we watch from the bottom to the top
of the bottle we can see a sedimentation. At the bottom there is a dark blue
color. This color shows us that there were organic matter and calcium sulfate.
Above of the dark
colors, we can see the iron (III) sedimentation of the orange color. At the top, we can
find a brown color and small holes which are wrecks gases produced by
cianobacterians formations.
We compare our bottle
with the other bottle which is at the darkness.
At first sight, this
bottle which was at the darkness is grey and smooth.
We can find three
zones. At the top, the water is cloudiness due to the oxygen which comes and
reacts with the organic matter and this produces water and carbon dioxide.
The second zone, we
can find a very little brown layer, which is in contact with the water. It
is result of iron oxide.
is result of iron oxide.
The third zone is the
biggest one and it is dark grey smooth, although at the bottom of the bottle we
watch some zones darker than the others. Is due to the iron (II) which reacts
with sulfhidric and it produces iron
sulfur (II). It has a black color.
The bottle on the
left is the one about which the darkness has influenced. However, the bottle on
the right is the one about which the light has influenced.
More information in the next post.
