2. Lime sulfur - Wikipedia

   en.wikipedia.org/wiki/Lime_sulfur

   The initial pH of the solution imposed by poorly soluble hydrated lime is alkaline (pH = 12.5) while the final pH is in range 11–12, typical for sulfides which are also strong bases. When the hydrolysis of calcium sulfide is accounted for, the individual reactions for each of the by-products are: 1 / 2 S 8 + H 2 O + 2 Ca(OH) 2 → 2 H 2 S ...

3. Thiosulfate - Wikipedia

   en.wikipedia.org/wiki/Thiosulfate

   Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S 2 O 2− 3. Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid , such as sodium thiosulfate Na 2 S 2 O 3 and ammonium thiosulfate (NH 4 ) 2 S 2 O 3 .

5. Calcium sulfate - Wikipedia

   en.wikipedia.org/wiki/Calcium_sulfate

   Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris , and another occurs naturally as the mineral gypsum .

6. Solubility chart - Wikipedia

   en.wikipedia.org/wiki/Solubility_chart

   The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

7. Sodium thiosulfate - Wikipedia

   en.wikipedia.org/wiki/Sodium_thiosulfate

   In pH testing of bleach substances, sodium thiosulfate neutralizes the color-removing effects of bleach and allows one to test the pH of bleach solutions with liquid indicators. The relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (the active ingredient in bleach) and in so doing becomes oxidized to sulfate ...

9. Flue-gas desulfurization - Wikipedia

   en.wikipedia.org/wiki/Flue-gas_desulfurization

   Fortunately, calcium sulfite can be oxidized to produce by-product gypsum (CaSO 4 ·2H 2 O) which is marketable for use in the building products industry. Caustic soda is limited to smaller combustion units because it is more expensive than lime, but it has the advantage that it forms a solution rather than a slurry. This makes it easier to ...
