The separation of gold from iron filings and sodium metal (a dangerous substance which will react with water in the air) could be done in two steps. Take a magnet and put it inside a plastic bag. Carefully and fully move the bagged magnet over the mixture, gently stirring it to insure the magnet can "reach" all the iron filings. When you are done, lift the magnet clear of the mixture, and you should have all the iron filings stuck to the magnet, which is inside the bag. If you carefully "invert" the bag, you'll then have the bag around the filings, which will still be stuck to the magnet with a layer of plastic bag between the two. Then just close the bag and remove the magnet. Your iron filings have been separated and bagged up. Now turn your attention to the gold and sodium mixture. Put them in a big heavy plastic container. If you *carefully* add water, you will get a chemical reaction. It is *critical* to put water in a drop at a time. (Yes, a drop at a time.) The sodium will react with the water and create sodium hydroxide, which is powerful base. It will also create a lot of heat, so you have to take all day to drop in the water so it won't melt your bucket. There will be some strong fumes, too, so take precautions. The bucket, because it is plastic, won't react with the sodium hydroxide. After you spend all day dripping the water into the mixture to react with all the sodium, you'll have a solution of sodium hydroxide with the gold in it. Strain this mixture and the gold will remain in the sieve. You'll need to wear a ton of protection to perform this evolution. Rinse your gold well to remove the traces of the sodium hydroxide and you're in business.

How do you separate a mixture of sodium chloride and aluminium filings?
To separate a mixture of sodium chloride and aluminum filings, you can use a magnet to separate the aluminum filings since they are magnetic, while the sodium chloride will remain unaffected. Alternatively, you can dissolve the mixture in water, then filter it to separate the insoluble aluminum filings from the soluble sodium chloride solution.
How do you separate sand iron filings naphthalene ball and sodium chloride?
Iron filings removed magnetically. Water will dissolve sodium chloride and suspend sand. Sand can be filtered out of the solution, and salt reovered by evaporation of water. Naphthalene can be removed separately if necessary by solution of mixture in alcohol.
Which separation technique would you use to separate the mixture of sodium chloride and water?
You can use the technique of evaporation to separate the mixture of sodium chloride and water. By gently heating the mixture, the water will evaporate, leaving behind the solid sodium chloride.
How do you separate a mixture of iodine solid and sodium iodide?
You can separate a mixture of iodine solid and sodium iodide by using the difference in solubility of the two compounds. Since sodium iodide is soluble in water while iodine is not, you can dissolve the mixture in water to dissolve the sodium iodide, leaving the solid iodine behind. The two can then be separated by filtration.
Is sodium chloride in water a mixture or compound?
Sodium chloride in water is a mixture. Sodium chloride is a compound made of sodium and chloride ions, while water is a separate compound made of hydrogen and oxygen. When sodium chloride is dissolved in water, it forms a mixture where the two substances remain chemically unchanged.

What is salt a mixture of?
Salt is a chemical compound known as sodium chloride, which is formed by the combination of sodium and chloride ions. It is not a mixture but rather a pure substance with a fixed chemical composition.
Which separation technique would you use to separate the mixture of sodium chloride and water?
You can use the technique of evaporation to separate the mixture of sodium chloride and water. By gently heating the mixture, the water will evaporate, leaving behind the solid sodium chloride.
How do you separate a mixture of sand sodium chloride and barium chloride?
first, add water to the mixture, barium chloride is soluble in water. then filter through and funnel and filter funnel. then add sodium sulphate, using the stove they will expand and separate. ( sodium cloride, and sand
Can sodium chloride be a component of a mixture to separate?
Yes, it is normal.

How do you separate a mixture of ion filate and sodium chloride?
Mix the mixture with water to dissolve the sodium chloride.Dip a magnet into the mixture to pick up all of the iron filings.Evaporate the water to retrieve the sodium chloride.
Is sodium chloride in water a mixture or compound?
Sodium chloride in water is a mixture. Sodium chloride is a compound made of sodium and chloride ions, while water is a separate compound made of hydrogen and oxygen. When sodium chloride is dissolved in water, it forms a mixture where the two substances remain chemically unchanged.
How do scientists separate the sodium out of sodium chloride?
When a mixture of 42% NaCl and 58% CaCl2 is electrolysed in Down'cell pure molten sodium metal is obtained.
How will you separate naphthalene from mixture of naphthalene and sodium chloride?
Naphthalene can be separated from sodium chloride by sublimation. When the mixture is heated, naphthalene will sublimate, turning from a solid to a gas, and can be collected separately from the solid sodium chloride.
How do you separate sufur and sodium chloride?
- Put the mixture in water. - Sodium chloride is soluble, sulfur not. - Filter the liquid. - Sulfur remain on the filter.
