i dont know please tell me someone, i know that it has been used to make ink in the olden days but what else?
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
To separate a mixture of salt and sand, you can use the method of dissolving the salt in water and then filtering the sand out. If the mixture consists of iron filings instead of salt, you can use a magnet to attract and separate the iron filings from the sand. This method works since iron is magnetic while sand is not.
When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
Remove the salty water and desalinate by evaporation, leaving the salt crystals behind. Condense the evaporated water vapour back into a liquid (water). Pass a strong electromagnet repeatedly over the sand and iron (iron filings?) mixture until all the iron has been removed, leaving the sand grains behind.
One way to separate iron nails and salt is by using a magnet. Since iron is magnetic, you can move a magnet over the mixture and the iron nails will be attracted to the magnet, allowing you to separate them from the salt. Another method is to dissolve the mixture in water, as salt dissolves readily, and then use filtration to separate the solid iron nails from the dissolved salt solution.
Iron fillings can be separated: - with a magnet - after the dissolution of the mixture, by filtering
When you add table salt and iron filings together, they do not react chemically. The salt and iron filings will remain as separate entities in the mixture.
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.
To separate a mixture of sand, iron filings, and salt, you can use a magnet to remove the iron filings, then dissolve the salt in water and filter the sand out. Lastly, evaporate the water to obtain the salt.
First you want to get the iron filings out. You do this with a magnet.Next, put the sand-salt mixture in water. Stir well to dissolve the salt, then pour off the water. (If you really want to be slick about it, rinse the sand in plain water.)Then put the salt water in a shallow dish and let it evaporate.
Iron is separated with a (electro)magnet.Camphor is extracted with acetone.
A heterogeneous mixture is a combination of two or more substances that are not uniformly distributed and can be visibly distinguished. To separate salt and iron filings, you can use a magnet to attract and pull out the iron filings, leaving the salt behind. Alternatively, you can dissolve the salt in water and then use filtration to separate the undissolved iron filings.
