Hello, first of all I know that you shouldn't put carbonated drinks in a copper bottle, I explained this to my colleague who then filled my bottle with mineral water and left it for a whole day, I've often heard that components could then dissolve from the bottle and that this is harmful to health,…
Why do copper sulfate crystals form in copper sulfate solution?
Copper sulfate is classified as highly toxic even in small amounts. We bought mineral tablets that contain, among other things, 150 micrograms of copper sulfate per tablet. Is this amount harmless?
Good afternoon, Did I solve the following task correctly? Task 2 [a) What happens when white copper sulfate comes into contact with water? ] When white copper sulfate comes into contact with water, it reacts with considerable heat to form blue copper sulfate. This is an exothermic reaction (Delta H < 0) because energy is…
Unfortunately, I can't find any real answers on the Internet.
This was the task: Now to my question: The copper sulfate attracts water and then turns blue. Our teacher told us in the lab that first, water of hydration (CuSO4 • H2O) is formed, followed by copper sulfate tetrahydrate (CuSO4 • 4H2O). Can someone explain to me in more detail how and why this happens?…
Hello, I wanted to ask why an iron nail turns pink when you dip it in copper sulfate.
geg: 800 microliters of copper(II) sulfate solution -> How much copper is in it? gladly with calculation method, thanks!
So, in chemistry, we were given a homework assignment. It's a worksheet. The fourth problem says: 'Write down the reaction scheme for the conversion of blue copper sulfate to white copper sulfate.' There's nothing about it in the book, and there's nothing helpful online either. Can someone please explain this to me or just write…
Hello, I'm hoping there are some chemists around here who can help me. I bought some copper(II) sulfate pentahydrate and experimented with it a bit, just for fun, like flame coloring and such. Then I added sodium chloride to a copper sulfate solution. The initially blue solution gradually became greener until it was actually green….
Good evening everyone. I need some copper for an experiment in chemistry class. Where can I get some quickly and for free?
Hello everyone. My question for a school project is the following: Is there copper in cell phone charging cables, HDMI cables, USB cables, etc.? Lg
