February 24, 2019How would you make copper sulfate without sulfuric acid?
Well, first of all you can buy copper sulphate at most common hardware stores (not near me but I've heard you can). If you can't use sulphuric acid I don't suppose you have copper fluoride and magnesium sulphate? Mixing these creates a solution of copper sulphate. My next thought would be to try and crystallise it out by adding a very hot solution of copper chloride/acetate to a very hot solution of sodium/potassium/ammonium sulphate and letting it cool. If you see deep blue crystals those should be (not very pure) copper sulphate. More on reddit.com

January 28, 2018Some copper sulfate crystals I grew at home, the process, and what I learnt along the way.
It was a Friday three years ago when I first fell in love with crystal growing, and indeed, with chemistry. That day, my high school Chemistry teacher asked us to make copper sulfate via an acid base reaction, and leave the solution to dry to obtain crystals. I thought the *crystals* were going to look like powdery grains of sand. Imagine my surprise when she showed us the large, sparkling crystals we had grown the next Monday. Over the course of the next few years, I would learn more about the art of growing crystals with chemistry, and the more I discovered, the more fascinating it became. For instance, you can control the shape of the crystals by adding impurities, crystallize insects with it, and by mixing with the right compounds, create an entirely different crystal altogether. However, interesting though this hobby was, I also realized that there was a lack of information regarding it online. There were certainly articles on how to grow copper sulfate crystals, but they were generic and lacked detailed information. There were no suggestions on what to watch out for, the dangers, and the common errors. After experimenting for 3 years, I decided to write a detailed guide and pictures of my own crystals to guide people who are as interested in it as I am, and hopefully to get more people to love chemistry too. You can find it here . I'm really looking forward to hearing what you guys think. Feel free to ask me any questions or give suggestions. More on reddit.com

From Wikipedia, the free encyclopedia
Copper(II) sulfate ("sulphate" in most Commonwealth nations) is the chemical compound with the formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, while the pentahydrate, which is most commonly encountered salt, is bright blue. This hydrated copper sulfate occurs in nature as the mineral is called chalcanthite. The archaic name for copper(II) sulfate is "blue vitriol" or "bluestone"

December 1, 2019 - As the least costly aquatic herbicide, copper sulfate pentahydrate (Figure 1) is widely used for short-term management of algae. It is ineffective in the long term unless combined with other management methods. Both filamentous and planktonic algae are simple plants with the capacity to rapidly reproduce and become overabundant.
