Calcium Hypochlorite - an overview | ScienceDirect Topics
Calcium hypochlorite contains 66% chlorine, and has been used in inline dispensers for hose-down appliions. Chlorine dioxide is an unstable compound that is prepared by mixing dilute solutions of chlorine and sodium chlorite but is a stronger oxidizing agent
Calcium chloride - Wikipedia
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2

(i) Calcium reacts in cold water more quickly than magnesium because more energy is required to remove the outer electrons in magnesium. This occurs even though calcium atoms have a greater nuclear charge. Explain why more energy is required to remove
chlorine (Cl) - David Darling
Chlorine reacts with most organic compounds, replacing hydrogen atoms (see alkyl halides) and adding to double and triple bonds (see section "Reactions of chlorine" below). Chlorine was discovered by Carl Scheele in Uppsala, Sweden, in 1774.
What will be the reaction between calcium carbonate …
They would not react in the sense of forming a new compound. Calcium carbonate is already the least soluble of the possible products and as such would always precipitate first in any kind of reaction involving dissolved quantities of these product
Water Handbook - Chlorine & Chlorine Alternatives | SUEZ
"Available chlorine" is an expression of the equivalent weights of oxidizing agents, with chlorine gas as a basis, similar to the expression of alkalinity in terms of calcium carbonate equivalents. The term originated from the need to compare other chlorine-containing compounds to gaseous chlorine.

calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.

Calcium reacts readily halogens forming the corresponding dihalides. The reactions with fluorine and chlorine are exothermic while the reactions with bromine and iodine are endothermic. Ca (s) + F 2 (g) CaF 2 (s) Ca (s) + Cl 2 (g) CaCl 2 (s) [6] Ca (s) + Br 2 (g) 2
Demonstrations - Calcium + Water
After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide. The presence of the hydroxide is demonstrated by the addition of a few drops of phenolphthalein indior, which turns the solution pink, indiing that the solution is basic.
Chlorine dioxide - Wikipedia
Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 C, a reddish-brown liquid between −59 C and 11 C, and as bright orange crystals when colder. It is an oxidizing agent, able to transfer oxygen to a variety of substrates, while gaining one or more electrons via oxidation-reduction (redox).

Chlorine reacts with calcium hydroxide to give a mixture of calcium hypochlorite (bleaching powder), calcium chloride and water. 2Ca(OH)2 + 2Cl2 → Ca(OCl)2 + CaCl2 + 2H2O Chlorine is highly electronegative. It has a very high affinity for hydrogen to such an extent that it reacts explosively with hydrogen, emitting heat and light in the process. H2 + Cl2 → 2HCl Although both these
Redox reaction of hydrogen sulfide and chlorine
In this reaction, the H 2 S is changing into ‘S’ i.e, hydrogen is being removed from hydrogen sulfide. Removal of hydrogen from a substance is known as oxidation. Hence hydrogen sulfide is being oxidized to sulfur. Further, chlorine (Cl 2) is changing to HCl i.e, addition of hydrogen.) is changing to HCl i.e, addition of hydrogen.
