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.
To separate ammonium chloride from a mixture of ammonium chloride and sodium chloride, you can dissolve the mixture in water to form a solution. Then, heat the solution to evaporate the water, leaving behind solid ammonium chloride due to its lower melting point compared to sodium chloride. This process is known as crystallization.
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.
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.
Ammonia gas is created when you heat up a mixture of sodium hydroxide solution and ammonium chloride solution. This reaction is known as the ammonium chloride and sodium hydroxide reaction.
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 is NaCl. Ammonium nitrate is NH4NO3.
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.
I suppose that the best method is a repeated crystallization/recrystallization process.
The experiment will not work because sodium chloride does not sublime. Ammonium chloride appears to sublime upon heating. However, this process is actually decomposition into ammonia and hydrogen chloride gas. NH4Cl + heat → NH3 + HCl (Wikipedia)
Ammonium chloride > sodium chloride > sucrose Sucrose > sodium chloride > ammonium chloride Sodium chloride > ammonium chloride > sucrose The correct answer is option 1: Ammonium chloride > sodium chloride > sucrose.
No sodium chloride is not a heterogeneous mixture.
Heat it until the ammonium chloride sublimes. Then add distilled water to what's left, stir, allow the solid to settle to the bottom of the dish, and decant the liquid. Repeat that 3 times. That'll extract the sodium chloride (salt) from the silicon dioxide (sand), because the NaCl is soluble in water. Then heat the salt water solution carefully until all the water is evaporated. Then heat the sand to dry it out.
