How to Set up Gravity Filtration

0:05i want to set up gravity filtration as one of the technique that is used in general

0:11chemistry and also in organic chemistry but for setting up the gravity filtration

0:19we are going to use small ironing to attach to ring the stand this is a support

0:27for a glass funnel that we are using for our for the filtration now to prepare the

0:36filter paper i take one large filter paper i fold the filter paper in half

0:45fold it in half again for second time side fold it in half first i fold it in half again

0:53second time then i open it one part to one side three parts to the other side what i

1:02don't want to happen like if someone to fold is like this and it's going to make a hole

1:08like this crystals or precipitate is going to pass through so what you need to do after you

1:15fold it twice one part in one side three parts on the other side you basically made a paper funnel

1:22you place it in the class in the glass funnel see it's not staying still and in order for this to

1:29stay still i'm going to add few drops of water when i add some water to the filter paper the

1:40filter paper is going to stay still gravity filtration is different from decanting decanting

1:47the the method for for is another technique which we will talk about in different experiments but

1:54here we are doing filtration so we want to separate the solid from the liquid we want

1:59the solid to go on the filter paper and the liquid would pass through the filter paper

2:04so I am going to pour the mixture through the filter paper and because i want to transfer both

2:12of them through the to the filter paper i can mix it so to make sure that everything would go

2:18otherwise the solid piece especially in this case that we have sand for this part of the experiment

2:25with sand and copper sulfate the sand is heavy and it's going to stay in the beaker so we are mixing

2:32it agitate mix and then add to the filter paper store it well and add and if you have leftover

2:44in the beaker leftover of solid in the beaker keep adding the solvent that you were using

2:52and pass it through the filter paper to make sure that everything is going to be

2:57transferred to filter paper now with this we have separated the

3:04solid from the liquid the liquid portion now is in the beaker we have a solution of copper sulfate

3:12is a blue color solution in the copper in the beaker and the span is on the filter paper now if

3:20you were going to recover this major mass or the procedure asked for further steps you can take it

3:29out of the filter paper take the filter paper out of the funnel place it and watch glass let it air

3:37dry then you have dry sand for this liquid it can be evaporated and then you end up with the copper

3:45sulfate because that's the separation technique or physical means for separation techniques
