Rehydrating Copper (II) Sulfate
Someone gave me an idea and I want to do it:
See what he said? Let’s follow him.
The last time we used test tubes and destroyed all of them! So I’m going to use a beaker.
I put the copper sulfate in it and going to burn it.
It’s white now. I’ll drop water on it.
I’m guessing that it works like this: I took the water molucles out by evaporating the water, now I have this white dust without water in there, and when I added the water, it turned back to blue (it’s like adding the water molucles back to it). This is why I love chemistry. It’s so awesome!
