  2. Calcium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_hydroxide

    Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction: Ca(OH) 2Ca 2+ + 2 OH −. The solubility is affected by the common-ion effect. Its solubility drastically decreases upon addition of hydroxide or calcium sources.

  3. Strong electrolyte - Wikipedia

    en.wikipedia.org/wiki/Strong_electrolyte

    In chemistry, a strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution. Originally, a "strong electrolyte" was defined as a chemical compound that, when in aqueous solution, is a good conductor of electricity. With a greater ...

  4. Lime sulfur - Wikipedia

    en.wikipedia.org/wiki/Lime_sulfur

    By rewriting the last reaction in the inverse direction one obtains a reaction consistent with what is observed in the lime sulfur global reaction: 3 / 8 S 8 + 2 H 2 O → 2 H 2 S + SO 2. In alkaline conditions, it gives: 3 / 8 S 8 + 2 H 2 O + 6 OH − → 2 S 2− + SO 2− 3 + 5 H 2 O. and after simplification, or more exactly recycling, of ...

  5. Hydroxide - Wikipedia

    The formula, Cu 2 CO 3 (OH) 2 shows that it is halfway between copper carbonate and copper hydroxide. Indeed, in the past the formula was written as CuCO 3 ·Cu(OH) 2. The crystal structure is made up of copper, carbonate and hydroxide ions. [37] The mineral atacamite is an example of a basic chloride. It has the formula, Cu 2 Cl(OH) 3.

  6. Calcium sulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfite

    The tetrahydrate crystallizes as a solid solution of Ca 3 (SO 3)2(SO 4). 12H 2 O and Ca 3 (SO 3)2(SO 3). 12H 2 O. The mixed sulfite-sulfate represents an intermediate in the oxidation of the sulfite to the sulfate, as is practiced in the production of gypsum. This solid solution consists of [Ca 3 (SO 3) 2 (H 2 O) 12] 2+ cations and either ...

  8. Calcium hydrosulfide - Wikipedia

    en.wikipedia.org/wiki/Calcium_hydrosulfide

    Calcium hydrosulfide is the chemical compound with the formula Ca(HS) 2 or CaH 2 S 2. [1] It is formed from the reaction of calcium hydroxide or calcium carbonate with hydrogen sulfide: [2] Ca(OH) 2 + 2H 2 S → Ca(HS) 2 + 2H 2 O CaCO 3 + 2H 2 S → Ca(HS) 2 +H 2 O+CO 2

  9. Calcium bisulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_bisulfite

    A calcium bisulfite liquor solution is used in the process of converting dihydroquercetin in tree bark pulp and then converting dihydroquercetin to a usable form: quercetin. Calcium bisulfite is not the optimum bisulfite compound for this reaction since the calcium ions can be removed from the calcium bisulfite solution during the reaction ...
