2. 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.

3. Zinc sulfide - Wikipedia

   en.wikipedia.org/wiki/Zinc_sulfide

   Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite . Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.

4. Solubility table - Wikipedia

   en.wikipedia.org/wiki/Solubility_table

   The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.

5. Liquid scintillation counting - Wikipedia

   en.wikipedia.org/wiki/Liquid_scintillation_counting

   Liquid scintillation counting is the measurement of radioactive activity of a sample material which uses the technique of mixing the active material with a liquid scintillator (e.g. zinc sulfide), and counting the resultant photon emissions.

6. Marsh test - Wikipedia

   en.wikipedia.org/wiki/Marsh_test

   The most common test (and used even today in water test kits) was discovered by Samuel Hahnemann. It would involve combining a sample fluid with hydrogen sulfide (H 2 S) in the presence of hydrochloric acid (HCl). A yellow precipitate, arsenic trisulfide (As 2 S 3) would be formed if arsenic was present. [6]

7. Qualitative inorganic analysis - Wikipedia

   en.wikipedia.org/wiki/Qualitative_inorganic_analysis

   The reagent used can be any substance that gives S 2− ions in such solutions; most commonly used are hydrogen sulfide (at 0.2-0.3 M), thioacetamide (at 0.3-0.6 M), addition of hydrogen sulfide can often prove to be a lumbersome process and therefore sodium sulfide can also serve the purpose. The test with the sulfide ion must be conducted in ...

8. Sphalerite - Wikipedia

   en.wikipedia.org/wiki/Sphalerite

   Sphalerite is a sulfide mineral with the chemical formula (Zn, Fe)S. [5] It is the most important ore of zinc.Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits.

9. Zinc - Wikipedia

   en.wikipedia.org/wiki/Zinc

   Zinc metal is produced using extractive metallurgy. [111]: 7 The ore is finely ground, then put through froth flotation to separate minerals from gangue (on the property of hydrophobicity), to get a zinc sulfide ore concentrate [111]: 16 consisting of about 50% zinc, 32% sulfur, 13% iron, and 5% SiO 2.
