The acidity concept and modern science absurdities….

Contrary to a lot of other phenomena where an excited or ionized species return
to ground states with photon emission, in case of acid dissolved in water
charges appear and extinct in a very strange way.
More precisely, no photons were observed to be released in this case, even in
such solution a continuous equilibrium between charge generation and extinction
is accepted to happen.
This is not a singular oddity…

If the polarity of water is the reason for molecule ionization, a strange
situation appears when hydracids water solutions are prepared.

A new definition of acidity is proposed and in the book, the concept of basicity
is revised too.

Hello,

With the new proposed model of covalent bound, already posted in a previous
message,  the face of organic and inorganic chemistry changes completely.

On the elkadot site some exemplifications of common organic reaction are
presented.



New proposed mechanism of radical substitution:

New proposed mechanism for aromatic substitution:

Covalent bound and absurdities of modern science

A cornerstone for quantum mechanic and entire chemistry is represented by actual
description of chemical bounds.
It is accepted that covalent bonds are formed as a result of the sharing of one
or more electrons between atoms. There is no conceptual explanation, how the
electrons participating at bound are moving around or between atoms. As usual,
quantum mechanic, in its variants, Valence theory and Orbital Molecular theory,
predict a certain probability for electrons to be in certain region of space,
without an intuitive explanation.
  In proposed model, a covalent bound is formed as result of coupling between
electron magnetic moments. No sharing of electrons is allowed, no increased
density of electrons in the space between atoms participating at bound
formation. Quantum mechanic is ruled out and an analogy with an interaction
between two macroscopic magnets can be made. The interaction between these
magnetic moments can explain the covalent bound formation. Their spatial
orientation can explain the orientation of covalent bounds in space.
The old text about covalent bound is corrected and improved at new link :
http://www.elkadot.com/chemistry/COVALENT%20BOND.htm


Ionic, coordinative bound and metallic bound are revised in the new chemistry
book, too.

Daniel cell and absurdities of modern science


A critique analysis of Daniel's cell is provided at following link (improved):

http://www.elkadot.com/chemistry/Daniel%20cell%20and%20the%20salt%20bridge.htm

The old Daniel cell and some of its variants have not get a coherent explanation
in actual orthodox science.

A modern variant, using a salt bridge between half cells, is found to be
non-functional. More precisely, the salt bridge, formed by an inert salt, does
not participate at general reaction chain, so no reaction takes place inside
such cell. Such cell can be leaved in short-circuit position for months without
a significant consume of electrodes or without solution color modification. Of
course, in this case, there is a small residual current due to the reaction
between Zn and water, but this is a secondary reaction and not the expected
reaction able to produce the expected current.

  Further, the actual explanation can be proved to be false using simple chemical
reactions able to be performed in any low level school laboratory.

Sorin Cosofret

Ionization energy, work function and absurdity of modern science

The neglected ionization energy variation for isoelectronic series can reveal
more useful information about electrons structure; the problem is these data are
in contradiction with actual quantum theory.
The quantum prediction for work functions values are in contradiction with
experiments; for metals, ionization energy and work function must be equal but
in reality they are not.
For other classes of compounds quantum mechanic fails again to predict
something. A striking example is the case of metallic oxides having work
functions values smaller then metals. It is outrageous how a covalent or ionic
bound liberate electrons easier then a metallic bound in frame of actual
physics.

The improved link:
http://www.elkadot.com/chemistry/Ionization%20energy%20and%20work%20function.htm

I think the message can to be posted on all kinds of physics and chemistry
discussion groups as far is dealing with foundation of our modern science.

Sorin Cosofret

Concentration cells and absurdities of modern science

A critique analysis of concentration cell and electrode phenomena is provided at
following link:
http://www.elkadot.com/chemistry/Concentration%20cell%20and%20the%20salt%20bridg\
e.htm

In the frame of actual physical chemistry it is found that concentration cell
works without a coherent explanation. Further, the actual explanation can be
proved to be false using simple chemical reactions able to be performed in any
low level school laboratory.
A new experiment able to clarify some of electrode phenomena is proposed.

Hi there,

I have worked as a chemist analyst in QC labs. of Iranian
pharmaceutical companies such as Sandoz- Iran and Iran- Organon. I have
have done analysis based on USP, Eup and BP. I was analysing raw
materials and finished products. As far I remember the Identification
tests, Assay yests, and determination of ingredientd of drugs was so
important by USP. The rest let me be up to dated please. Now I am
living in the Netherlands and I am suffering from unemployment because
they are so racist and do not offer such jobs to forigners under the
title of "language problem" and "over qualified" specilly when they are
graduated from a foriegn unversity even in USA. I am graduated from
Texas in 1978 and I am very disappointed that I came to the
Netherlands, but unfortunately I had no any other option.

Thanks,

M. Bazrafkan

Hi all,
Do you know what is the main focus of the united states pharmacopeia?

  it is very easy to use redox titration to determine iron in presence
of its oxide.
1ST STEP:(TOTAL IRON CONTENT)
1-first dissolve your sample in 5 ml CONC HCL
2-heat to boling, then add 10 % stannous chloride drop by drop till
colorless , then add one drop excess stannous chloride.
3-dilute to 100 ml with distilled water
4-add 5 ml 10% HgCL2, stirr well till the formation of  silky white
ppt.
5-add 10 ml Zimmermanns reagent
6-titrate against 0.1N KMnO4 till pink color.(EP1)

2ND STEP (IRON OXIDE ALONE)
1- dissolve the same weight of your sample in  dil H2SO4
2-Titrate against 0.1N KMnO4 till pink clor(EP2)

IRON ONLY= EP1-EP2

if there is elemental iron mixed with iron oxide, they can be

The analysi part is fairly straight forward. I need to know how to dissolve the
