How to separate the substances of sodium chloride, ammonium chloride, lead chloride and iron fillings from a mixture.
Magnet used to separate iron filings.
PbCl2 is not soluble in waer.
Gently heat NaCl/NH4Cl to vaporize NH4Cl and condense the vapor on a cool surface above.

To separate the substances of sodium chloride, ammonium chloride, lead chloride, and iron filings from a mixture, you can employ the following methods:
1. Magnetic separation: First, use a magnet to separate the iron filings. The magnet will attract the iron filings, allowing you to easily separate them from the mixture.
2. Filtration: Next, you can use a filtration process to separate the solid compounds (sodium chloride, ammonium chloride, and lead chloride) from the remaining liquid.
a. Set up a funnel with filter paper or a filter funnel, and place it over a beaker.
b. Slowly pour the mixture through the funnel. The liquid, which contains the dissolved sodium chloride and ammonium chloride, will pass through the filter paper, while the solid lead chloride will be retained on the filter paper.
c. Collect the filtrate (liquid) in the beaker and keep it aside for further separation.
3. Crystallization: To separate sodium chloride from ammonium chloride, you can use the process of crystallization. Here's how:
a. Heat the filtrate obtained from the filtration process slowly to evaporate the water content. It is recommended to use a water bath or a heat source with controlled temperature to avoid excessive heat.
b. As the water evaporates, sodium chloride will start to crystallize because it has a higher solubility than ammonium chloride at room temperature.
c. Let the solution cool down and collect the sodium chloride crystals that have formed. This separation is based on the difference in solubility between sodium chloride and ammonium chloride.
Note: Be cautious while handling lead chloride as it is toxic. Follow proper safety precautions such as using gloves and working in a well-ventilated area.
By following these methods, you can successfully separate the substances of sodium chloride, ammonium chloride, lead chloride, and iron filings from the mixture.
