I am just curious how could make Na Cl (salt) ?
My friend told me you could by mixing Sodium Phosphate and Iron chloride.
Can you guys tell me any more ways that I could make Na Cl except Sodium Phosphate and Iron chloride?
a balanced equation would help me understand

Weird idea to make kitchen salt. 
It is more expensive to prepare than just buy a kilo from your local store. 

If you want to make some of it anyway, there are many possibilities. The easiest one I can think of is to react hydrochloric acid and sodium hydroxide:
NaOH + HCl  NaCl + H₂O
You have to do this reaction in water (or else, HCl would be a gas). At the end, you need to evaporate water to get your product.

aw I just figured that out

Are there any other ways

[cth]

Yes.
If one of the salts forming is insoluble, it will precipitate. You just have to filter it off and evaporate water to get NaCl.

For example, reactions in water:
* 2NaI + PbCl₂  2NaCl + PbI₂
PbI₂ has a low solubility in water. So you filter it out and you're left with salty water (and still some traces of Pb₂).
* Na₂SO₄ + BiCl₂  2NaCl + BiSO₄
BiSO₄ will precipitate.
* Na₂(oxalate) + CaCl₂  2NaCl + Ca(oxalate)
Calcium oxalate is damn insoluble in water.

If you don't want to use water, you can use sodium metal or hydride:
* Na⁰ + Cl₂  2NaCl
This reaction is between a solid and a gas, so it will react only at the sodium surface.
* NaH + HCl  NaCl + H₂
Hydrogen is a gas that just flies away
* NaNH₂ + HCOCl  NaCl + HCONH₂
You could use an acyl chloride and sodium amide.

There are many many other ways. But the easiest way is to go buy it. No bother making it

Benzene diazonium chloride + Ethylsodium
C6H5N2Cl +NaC2H5--> NaCl + C6H5C2H5

hydrazinium chloride + NaOH
N2H5Cl +NaOH-->N2H2 +NaCl +H2O

1-chlorobutane + sodium nitrite
C4H9Cl+NaNO2--> C4H9NO2 +NaCl

2 Sodium azide + cyanogen chloride
2NaN₃ + CNCl  --> NaCl + NaCN₇  (yes, CN₇ is correct before anyone asks)

2Na +Cl2--> 2NaCl

Possibilities are infinite

[cth]

2 Sodium azide + cyanogen chloride
2NaN₃ + CNCl  --> NaCl + NaCN₇  (yes, CN₇ is correct before anyone asks)

NaCN₇?! 
I've never seen this one before, and it looks interesting. What is its structure?


I tried to guess:
CNCl + N₃^- will form a 5-chloro-tetrazolate compound, like the picture of a tetrazole ring below with one added chlorine attached on the carbon.

tetrazole ring

But then, I don't see where a second N₃ would react to form CN₇^-. I couldn't find it in SciFinder.

Thanks for this unusual compound 

[408]

Azidotetrazole, a sexy beast of a compound.       

First equiv of azide makes cyanogen azide
second equiv cyclizes to azidotetrazole.

Nice, thank you. I see I had guessed half of the compound. 

It would be nice to use as a ligand to complex transition metals, but its instability is a big problem. Nevermind, it keeps me thinking about ligands possibilities.

[408]

Nitrotetrazole exists as a ligand in many metal complexes

Ex :
Fe(NT)6 (4-) (sodium and ammonium salts)
Co(NH3)4(NT)2 ClO4 "BNCP"
Both are primary explosives of high quality.

Azidotetrazole complexes likely far too unstable
Even when large alkyl chains are hung off azidotetrazole, it is still exceeding impact, friction and spark sensitive, and this is after severely diluting the nitrogen content.

General trend for 5-substituted tetrazole explosiveness: more electron withdrawing, more sensitive

N2+ (explode above 2% concentration in aqueous solution ) >N3 > NO2  >NNO2 >NH2
