Calcium Hypochlorite: A Pool Chemical And Much More
Calcium hypochlorite is a white solid that is added in granular or tablet form to pool water to kill germs that can make swimmers sick. Used properly, by well-trained pool operators, this compound destroys germs that are capable of causing numerous health problems for pool users--diarrhea, swimmer''s ear (a nasty earache) and various respiratory, skin and wound infections.

Hard Water Experiment - Layers of Learning
Hard water just means water that has minerals in it. The minerals usually include calcium, magnesium, and others that are dissolved in the water. You can’t usually see whether or not you have hard water just by looking at it, but you’ll probably be able to tell
Reactions of Group 2 Elements with Water - Chemistry …
Calcium, for example, reacts fairly vigorously and exothermically with cold water. Bubbles of hydrogen gas are given off, and a white precipitate (of calcium hydroxide) is formed, together with an alkaline solution (also of calcium hydroxide, which is slightly water-soluble).

Background Information: hydrochloric acid is a clear, colourless, highly-pungent solution of hydrogen chloride (HCl) in water. It is a highly corrosive, strong mineral acid with many industrial uses. Hydrochloric acid is found naturally in gastric acid. calcium carbonate is a chemical compound with the formula CaCO3.
Calcium carbide - Wikipedia
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is
Calcium Hypochlorite - an overview | ScienceDirect Topics
Nicholas F. Gray, in Microbiology of Waterborne Diseases (Second Edition), 2014Hypochlorite Hypochlorite was the original form of chloride used for the disinfection of drinking water. Known as chloride of lime, calcium hypochlorite (Ca(OCl) 2) is a solid which can be used as a powder, granules or in tablet form and is still widely used today at smaller WTPs.

acid-base behaviour of the period 3 oxides - chemguide
4/10/2018· For the remainder of the oxides, we are mainly going to be considering the results of reacting them with water to give solutions of various acids. When we talk about the acidity of the oxides increasing as you go from, say, phosphorus(V) oxide to sulphur trioxide to chlorine(VII) oxide, what we are normally talking about is the increasing strengths of the acids formed when they react with water.
