How to Separate Salt from Sugar Experiment

In other to successfully separate salt from sugar, you must have basic chemistry knowledge at least. It is very important that you are also familiar with some of the needed items for the process. What this write up will teach you is how you can successfully do it in three simple steps.

Part 1:  The Beginning

Step 1
Get pure alcohol. It is very important you should be careful with this as it can be highly inflammable. An example of pure undiluted alcohol is ethanol.

Step 2
If the sugar and salt are together inside water, you will have to look for a way to remove the water. You can do this by making use of steam bathe to get the water evaporated.

Step 3
You will need to look for a good heat source. You can make use of Bunsen burner. There are other options but this one can serve you best.

Part 2: Having the salt separated

Step 1
Use a cup to measure the salt and sugar. Please note that this should be in their dry mixture after the water has been removed through evaporation.

Step 2
Now pour some ethanol on the mixture. Note that the more mixture of salt and sugar that you have the more ethanol quantity that will be required. The sugar has to get dissolved without going through a process of saturation and the only way this can happen is that there has to be enough ethanol.

The best thing to do is that if your mixture seems to be much in terms of quantity, you will have to do it in different sections. Don’t do all at once in other to prevent a case of fire accident.

Step 3
Have the solution shuffled or stirred to allow the sugar settled down. If you mix it properly then the salt will be at the beaker’s bottom.

Step 4
Get a sieve and have a filter placed on it

Step 5
Now you will need to have your alcohol solution poured on the beaker; however, this time through your strainer or sieve.

Make sure that the strainer is able to cover all the salt.

Part 3: having the sugar heated

Step 1
Get a pot and then put water in it up to maybe half. After that, place your container in the pan or pot that you have provided.

Step 2
Have the sugar and ethanol placed on the container that is on the steaming room’s top.

Step 3
Continue heating gradually until you are sure that evaporation has taken place. That is all the alcohol has gone out and you have successfully separated salt from sugar.
