It is well known that common salt (NaCl) is easily dissoved in water. In the solution Na and Cl atoms are present as positive and negative ions. show that, due to high dielectric constant of water the resulting screening of the coulomb potential, the binding energy of NaCl crystal in water is smaller than the mean thermal energy of the free ions. Calculate the equilibrium separation of the ions of a hypothetical NaCl crystal in water and show the separation is larger than the van der waals radius of a water molecule to justify the solubility of NaCl

I know exactly how to attack this problem.


Before attacking the problem you have to be well prepared.
Wake up early at 5am in the morning and shower in luke warm water - I'm sure you are not used to showering in cold water but for best results use cold water or water having room temperature.

If you are a guy shave, and if you're girl shave your armpits.

Do not eat anything solid in the morning. You can have water and tea but no milk.

After waking up, you are supposed to recite the problem every 15 minutes.

The next phase of the attack plan is to invite your purohit to your house. He can only be wearing a chappal and his janai needs to have been changed within the last 12 hours. He cannot have eaten any dairy or meat product within the last 24 hours and he cannot have been married or had any children in the last 10 months.

Plan on the purohit being at your house at 10 am Nepali standard time. As soon as he settles in, have a female member of your household burn 50,000 incense stick on top of a rectangular space right in front of your main door or gate of size 5 feet by 5 feet soaked with fresh Gai ko gobur. If you can please verify that the Gai has not received any sperm deposits in the last 48 hours.

Now you are ready for the recital in front of the purohit. Both you and the purohit sit in the rectangle and start chanting your problem which you should have memorized by now to your purohit in an inaudible voice. Chances are that the language would not be familiar to your purohit in any case if your problem is in english. If you can, do hire an interpreter to interpret your question into sanskrit.

When the purohit spells out your name in sanskrit and calculates the distance between the moon and center of gravity of the cow whose gobur was used to purify the rectangular space, the stars are going to spell out the answer in morse code in the form of the blinking of the eye of the purohit. So you might as well get a morse code reader to translate the blinkings real time or you can simply videotape it and upload to youTube.com and hope that a generous morse code reader translates it to you for free.

I hope this instruction will help you attack the problem. Regarding solving the problem, I will provide you instructions at a later time.

Bhusan,
You made my day.............Lol

Sily lily,

sorry I don't know much about physical chemistry.

STEP 1: Semiotics of investigating & attacking the hypothetical NaCl crystal problem
Quantum chemsitry, hadron bootstrap theory, complex number theory, and chaos theory share the basic assumption that reality cannot be described in linear terms, that nonlinear -- and unsolvable -- equations are the only means possible to describe a complex, chaotic, and non-deterministic reality. These postmodern theories are -- significantly -- all metacritical in the sense that they foreground themselves as metaphors rather than as ``accurate' descriptions of reality. In terms that are more familiar to literary theorists than to theoretical physicists, we might say that these attempts by scientists to develop new strategies of description represent notes towards a theory of theories, of how representation -- mathematical, experimental, and verbal -- is inherently complex and problematizing, not a solution but part of the semiotics of investigating the universe.


STEP 2: Enveloping the Corresponding Singular ions of the Sodium Salt
In the first place, singularities-events correspond to heterogeneous acidi salt series which are organized into a system which is neither stable nor unstable, but rather 'metastable', endowed with a potential energy wherein the differences between series are distributed... In the second place, singularities possess a process of auto-unification, always mobile and displaced to the extent that a paradoxical element traverses the series and makes them resonate, enveloping the corresponding singular points in a single aleatory point and all the emissions, all dice throws, in a single cast.

STEP 3:Equilibrium separation of the ions of a hypothetical NaCl
In orthodox chemisttry terms, Derrida's observation relates to the invariance of the Einstein field equation Gμν=8πGTμν under non-linear space-time diffeomorphisms (self-mappings of the space-time manifold which are infinitely differentiable but not necessarily analytic). The key point is that this invariance group 'acts transitively'; this means that any space-time point, if it exists at all, can be transformed into any other. In this way the infinite-dimensional invariance group erodes the distinction between observer and observed; the π of Euclid and the G of Newton, formerly thought to be constant and universal, are now perceived in their ineluctable historicity; and the putative observer becomes fatally de-centred, disconnected from any epistemic link to a space-time point that can no longer be defined by geometry alone.

STEP 4: Calculation
(1) Na = Na+ + e- (positive, requires energy)
(2) Cl + e- = Cl- (positive, requires energy)
(3) Na+ + Cl- = NaCl (negative, releases energy)
(4) Na + Cl = NaCl

Na+ = Na2+ + e- (highly positive, requires a lot of energy)

Na2+ + 2Cl- = NaCl2

The electron configuration of the element sodium, Na, is the neon core
[Ne] + 1 electron in the 3s orbital. The element chlorine, Cl, is the neon
core [Ne] + 3s2, 3p5 one electron shy of the argon core, [Ar] 3s2, 3p6.
The combination of Na + Cl ------> Na (+1) + Cl (-1) results in a Ne core
for Na(+1) and a Ar core for Cl(-1). These filled shell configurations are
very stable energetically. There is no "driving force" for NaCl to bond
with another atom of chlorine. The addition of another atom of chlorine
would not be favored.

bhusan, this line from your text is my favorite: "He cannot have been married or had any children in the last 10 months." HAHAHA! That's amazing!

find out data of ionic radi of NA and Cl and show it is larger than van der waal distance.
