Understanding the nature of pH has bedeviled beginning (and not-so-beginning) chemistry students for nearly as long as chemistry has had students. It all seems so arbitrary, being the base-10 log of ...

Copper sulfate has been used in agriculture since the 1800s, at least. In the U.S. it is widely used as a fungicide on organic and conventional crops, and it is also found in some fertilizer products.
