To prepare pure crystals of cupper sulphate solution from given impure sample #11thchemistry

Hello friends, and welcome to my channel. So friends, I'm Sachin Shukla and you are watching A2J Practical. So, friends, today's experiment is basically experiment number 19. Experiment number 19 Which is the 11th chemistry? By the way, friends, let me give you one more piece of information. That I conduct all the practicals here Like 11th, 12th, all the practicals You can easily go to the playlist and check it out. And all the practical answers As it is, you can write the same. And you can write the same on your board. I only prepare all the experiments for you And it is done very well And all the answers are very accurate. So if you want You can check out all these playlists So today my experiment is going to start. It is the 11th, and the experiment number for the 11th is 19. What is basically in this That we have to prepare pure copper sulfate By impure solution That means we have some impure solutions of copper sulfate. With which we will prepare the pure solution So let me start the experiment For this, let me tell you, friends Why does it happen that when we dissolve and heat our copper sulfate? Then a pure crystal is generated. And we have to show it So let me start the experiment So, friends, I have a sample of copper sulfate. Which I must purify So basically we have to measure 5 grams of it. Our first step is That we have to measure 5 grams of copper sulfate I will tear it apart. Because it is displaying its weight Now what I will do I will take out 5 grams of copper sulfate. So I have taken out 5 grams of copper sulfate. Now What you have to do in the second point Dissolve at high temperature In the minimum amount of water Now what you have to do You must dissolve in water. As much water as can be added So I will add water little by little. And what I will do I will dissolve it. Clear friends And Now I am going to add water again. And what I will do I will dissolve it. So you have to add this much water To dissolve it Clear You can do it in a beaker. I am using a Chinese dish. Because I like Chinese food for heating But while dissolving it Dissolve it in the beaker. Clear Because some molecules May fall from here So use it in the beaker Finally, I have dissolved. Copper sulfate solution in water Now you have to heat it. It will dissolve completely. Then you have to evaporate one third of it. And after that Filter it Cool it Pure crystal will be generated Clear We have to dry it. So let's start Now I will turn on the burner. And this is Tripod stand And this is clay. You can heat it directly. So friends Now I am going to Heat it. Why Because it has Dissolved impurities And after that I will filter it. So that Dissolved impurities Will be removed easily For this I am using Filtrate You can see Filter paper You have to fold it like this And you have to Stick it like this Like this You have to keep it here And when it will heat I will filter it. Now I have to Filter it So that dissolved impurities will be removed So that Dissolved impurities will be removed. You can see It has been filtered. So now I have to add Filtrate solution And until Evaporate one third of it You have to heat it. I'm heating it directly. So that one third of it evaporates Now it is here So now Evaporate one third of it It has started boiling. You can see We'll let it boil. Until one third of it evaporates You can see It has started boiling. You can see I have to keep Filtrate ready And I have to filter it You have to arrange it like this Fold it like this And keep it ready As soon as it comes I will filter it. I will check it. If one third of it evaporates You have to remove it You can see It has evaporated one third of it. We will let it heat up further. You can see It has evaporated one third of it. Little liquid remains. If one third of it evaporates You have to filter it And after filtering You have to Keep it cool It has been filtered. Now I will Keep it cool And crystals will begin to form Now I will Let it cool down So the cooling will be fast. I'm putting it in water. To cool it down You can cool it naturally If you want What I will do I will filter it. I'll set it up. Now I will Remove it With the help of a glass rod You can remove it The crystal Which has formed With the help of a glass rod You can remove it. You have to remember I am not removing it. You have to remove it If you want You can press it with your hand To remove the liquid Now I will show you the crystal. You can see The crystal You can see the crystal. I have so many crystals. These are pure crystals. This is the crystal of copper. If you want to dry it I will tell you the method. You have to keep it here So that the heat from the wire gauze Will come down You must keep the copper sulfate. You have to dry it. With the help of its heat The heat comes down With its help It will get dry. You can see the drying process. You have to dry off in your college You must keep the wire gauze.
