Interesting results in this prac. Why did the Copper Sulphate appear entirely disolved, but when cooling, you could clearly see the particle reforming? Check out the video. Your thoughts?

The video is quite interesting. It looks different when you see it from the camera.
ReplyDeleteWhen the test tube was hitted, the copper sufate dissolved but when it cooled down it was visible.
ReplyDeleteit is interesting to see copper sulfate getting heated. inside the copper sulfate water we can see that there are bit whitish stuffs and this happens because blue copper sulfate has the water of hydration. Heating it will drive the water off and it will change the colour since the Oxygen atoms in the water is no longer complexed with copper sulfate atoms.
ReplyDeleteWhen it is heated,the copper sufate became invisible but when it cool down the copper sufate became visible
ReplyDeleteThe copper sufate becabe soluble when it is heated but when it cool down the copper sufate became insoluble
ReplyDeleteI think what happened was that, when copper sulfate was heated, it becomes transparent and when it cooled down, it goes back to its original state.
ReplyDeleteI think that when you heated the copper sulfatte the particles inn their began to turn into gas particles so the particles were invisible however when you let it cool down the particles turned back into it's original self
ReplyDeleteWhen the test tube was heated, the copper sulfate dissolved, but when it cooled down, it was visible again.
