Water is a polar molecule. What this means is that the electrons that hold it together are not shared equally. Water is made up of one oxygen atom and two hydrogen atoms. They are joined by covalent bonds, which means that the atoms share electrons to fill their outer shells and become stable. In this case, the electrons are not shared equally...they spend more time around ...
Mineral Salts Chemical Explanation
What is the chemical explanation as to why salts of water borne minerals scale on the inside of water piping, specifically carbon steel or stainless steel piping?
I know that more alkaline pH will produce many calcium, aluminum, iron, sodium, and magnesium salts in water systems.
But is there a particular pH range in which one of these mineral salts will be more prevalent than another? And what exactly is the mechanism that physically causes the scale to actually build-up and attach to the inside of a pipe? Is the some type of electro-potential difference kind of scenario.? Would aluminum salts tend to scale more so thatn calcium or magnesium salts?
I hope you can provide me a good detailed explanation ---- thank you so very much in advance. I want to learn and know as much as I can on this subject.
