Sometimes,
the things we know best are the things we know least. As we shift
into a world that has different meanings, the time has come to
rediscover what we believe we already know. The simple substance
water is not nearly as simple as we profess and the thyme has come to
explore water at a deeper level. Let's make a swan dive into the
deep end, then swim back to the surface level to integrate the
picture.
Water
is a molecule that consists of three atoms – a central oxygen atom
attached to two hydrogen atoms. In basic chemistry, we learned that
hydrogen has a weight of one atomic mass unit per atom and oxygen has
a weight of 16 amu. This means that water weighs 18 amu – thus it
has 18 grams per mole. This mole is a furry rascal who does chemical
accounting – he keeps track of atoms on a small ratio basis.
The
nature of chemical geography suggests that bound atoms arrange their
shapes to give all other atoms enough breathing room. The nature of
chemistry is such that atoms repel each other based on the
arrangements of electron pairs about a central nucleus which is made
up of protons and neutrons. Each nuclear subatomic particle, proton
and neutron, contributes one amu to the weight of an atom. The
electrons have no mass on the amu scale, however they govern the
arrangement of atoms in space.
Let's
talk about atoms in space. We know what space is, because we are all
stardust and space cadets who stare up at the sky at night and ask
what it is all about. We can see the stars and they are far out
there way far away from us – and we wonder sometimes. On the scale
of chemistry – the space units are likely just as far away from
each other as the stars are away from each other on this scale. When
we consider all that we know on many frames of the scale, we tend to
draw parallels between the things we know and the things we don't
know. This is convenient, but not proper.
We
need to say, 'I don't know' when we really don't know, instead of
making things up as we go along based on other things that we think
we know. Adjacent fractals have to be similar to each other in order
to get a blend in continuity, but as you move between Fibonacci
numbers, you find that the transitions are sharper at lower numbers.
Chemistry and sociology both work best when following group theory,
which is a math method of setting point groups in space. Sacred
geometry holds many answers to the questions of nature at all levels
of scale – the systems look the same but act very differently –
based on relative weight of participants.
Now
getting back to water – water has a bent shape where the angle
between the HOH bond is 109o . This is quite different
from the CO2 linear arrangement that has an OCO bond angel
of 180o. This is because water is based on a tetrahedral
shape – the same basic structure as carbon has in organic chemistry
with four bonds available. Water uses the extra two bonds available
to attach to adjacent water molecules. Water molecules tend to
cluster with other water molecules, because, we water molecules are
little guys in the total scheme of things. Water is not called the
universal solvent because of its charm – but because of its
strangeness – its quarks have quirks – but that pertains to
physics more than chemistry. Let's just say that water is ant sized
in relation to most biological entities that it deals with.
The
chemical composition of the ocean and the chemical composition of the
blood stream are very similar in the as above, so below sense of
things. Each has many dissolved salts that are ions conducting an
electric flow path that integrates entities that rely on the water
for sustenance. Water comes in swarms and attracts based on the
polarity of molecules – the distribution of extra or fewer
electrons to distribute balance between ions. A negative ion, called
an anion, has extra electrons that balance out atomic charges within
a molecule, while a positive ion, called a cation, has donated the
electron to the anion and does not wish to receive it back.
Water
solvates these ions and allows them to separate from each other, as
long as the electrostatic charge between the two (or more) ions
allows for the dissolution. There are measured tables of activity
constants and electrochemical potentials that suggest the relative
inorganic chemistry – the solubility product of an ionic compound
can be looked up conveniently. Aqueous chemistry is a field that
deals with mostly ionic compounds and is the basis for qualitative
analysis – the idea of analyzing the composition of a mixture of
things.
We
conveniently call these ions minerals and stop our chemical
investigations because we fear to tread into areas of biochemistry
and medicine. This is foolish because we assume that doctors
actually understand chemistry before they learn biochemistry – in
reel life that happens and we are addicted to movies. This life is
just like a movie and you are the supreme director – the more truth
that you really know, the better equipped you are to make good
decisions that affect your immediate future. This is enough
chemistry for one sitting – if you integrate the concepts here –
the next edition of the world of water will be more illuminating.
Namaste'
