residue by solid-liquid separation of a leaching slurry obtained from sulfuric acid leaching of nickel oxide ore under high temperature-high pressure condition, and applying a sulfidizing treatment by the above agent to the leaching liquid to generate nickel sulfide and the sulfidization rear ...
The note is easy. Just mixt 50 ml of sulfuric acid and 200 grams of very cold distilled water (or even frozen distilled water). But when it says "acidify the solution to Congo red paper", what does THAT mean? Congo red paper is a PH indicator paper I understand, but the color chang...
A. I do not know how to make sulfuric acid, but I do know how to make hydrochloric acid. You first do some electrolysis of brine to capture the hydrogen and chlorine gas given off. Then you combust the gases together to form hydrogen chloride, which you bubble through water. The resulti...
How Acid Rain Works By:Sarah Dowdey|Updated: Mar 12, 2024 Emissions of sulfur dioxide and nitrogen oxides react withwater vapor in the atmosphere to create sulfuric and nitric acids. Key Takeaways Acid rain, with a pH of 5.0 or less, is formed when pollutants like sulfur dioxide and ...
The sulfuric acid, in addition to removing the alcohol from the air, also might provide the acidic condition needed for this reaction. During this reaction, the reddish-orange dichromate ion changes color to the green chromium ion when it reacts with the alcohol; the degree of the color ...
How Do I Remove Water Stains From the Chrome Faucets in My Bathroom? How to Clean Lime Scale Off of Aluminum How to Remove Chemical Stains from a Stainless Steel Sink Vinegar (acetic acid) – Any type of vinegar will do, but 3 percent white distilled vinegar is the strongest unles...
Magnesium sulfate, often referred to as Epsom salt, is the magnesium salt of sulfuric acid and can be obtained by mining as kieserite or epsomite, or by dissolving magnesium oxide, magnesium hydroxide, or magnesium carbonate in sulfuric acid [50]. Magnesium ions are small, which favors their...

How is sulfuric acid prepared industrially?Sulphuric Acid:Sulphuric acid, having "molecular formula {eq}{{\rm{H}}_2}{\rm{S}}{{\rm{O}}_4} {/eq}", is assumed as a diprotic acid in which it has the property to release two protons. It is also used in neutralization reaction....
Plus, a lot of these drain cleaners are made with really strong stuff like lye and sulfuric acid, which can let off nasty fumes that are dangerous to breathe in. On top of harming nature, these store-bought drain cleaners usually cost more than natural options. ...
