a mixture of ammonium chloride and sodium chloride is a mixture of the both.
both being chlorides cannot chemically react with other.
So they can only be physically mixed.
Some examples of a buffer are mixture of ammonium hydroxide with ammonium chloride & mixture of acetic acid and sodium acetate.
The secret to separating any mixture is to find a property in which the mixed substances differ. For instance, sodium choride (NaCl)is very soluble in water; whereas, ammonium chloride (NH4Cl) is not. By putting the mixture of NaCl and NH4Cl in water (enough to dissolve all of the NaCl, but not enough to dissolve the NH4Cl), the NaCl will dissolve, and the solid left behind is ammonium chloride.
1. Evaporate the solution, water being removed. 2. Sodium chloride and ammonium chloride remain as a solid residue. 3. Heat this residue. 4. After 340 0C ammonium chloride is decomposed and gases released. 5. Sodium chloride remain single.
Sodium chloride and ammonium chloride can be separated either by sublimation or filtration or crystallization. Sublimation can be found on this site ------------ http://www.lenntech.com/Chemistry/sublimation.htm. I personally think that this method is the easiest.
Sodium chloride is NaCl. Ammonium nitrate is NH4NO3.
I suppose that the best method is a repeated crystallization/recrystallization process.
sublimation
Examples are: sodium chloride, potassium chloride, calcium chloride, ammonium chloride, ammonium phosphates, sodium carbonate, sodium sulfate, magnesium sulfate, cooper sulfate, magnesium chloride.
No
No sodium chloride is not a heterogeneous mixture.
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.
Gently heat - ammonium chloride will sublime on a cold solid surface
