It adds calcium ions (Ca2+) and sulfate ions (SO42-), but does not add or take away hydrogen ions (H+). https://doi.org/10.1021/acs.langmuir.8b00927, https://doi.org/10.1016/j.geothermics.2020.101899, https://doi.org/10.1016/j.cemconres.2020.106149, https://doi.org/10.1016/j.chemgeo.2019.119274, https://doi.org/10.1016/j.fluid.2019.03.006, https://doi.org/10.1016/j.calphad.2018.01.002, https://doi.org/10.2136/sssaj2017.12.0429, https://doi.org/10.1007/s10230-016-0398-0, https://doi.org/10.1007/s00603-016-1123-9, https://doi.org/10.1007/978-3-319-45669-0_12, https://doi.org/10.1007/978-3-319-45669-0, https://doi.org/10.1007/s00603-015-0827-6, https://doi.org/10.1016/j.cemconres.2014.10.009, https://doi.org/10.1007/978-3-662-43282-2_1, https://doi.org/10.1007/978-3-662-43282-2, https://doi.org/10.1016/j.hydromet.2011.03.007, https://doi.org/10.1002/9780470710777.ch8, https://doi.org/10.1002/9780470938416.ch6, https://doi.org/10.1007/s00254-006-0566-9, https://doi.org/10.1016/j.geothermics.2004.11.002, https://doi.org/10.1016/S0140-1963(18)31002-4, https://doi.org/10.1016/0009-2541(87)90022-2, https://doi.org/10.1111/j.1365-3091.1985.tb00737.x, https://doi.org/10.1016/0011-9164(84)87002-2, https://doi.org/10.1524/zpch.1977.104.1-3.041, https://doi.org/10.1016/0016-7037(69)90140-9, https://doi.org/10.1016/B978-0-08-009924-8.50007-6. Activity Coefficients of Strongly Complexing Compounds. & What type of reaction is Gypsum -> Anhydrite? Librarians & Account Managers. According to Lewry and Williamson, anhydrite hydrates via a two-stage reaction to first form bassanite at a relatively low reaction rate, and subsequently gypsum at a higher reaction rate. Anhydrite is orthorhombic and does not react with hydrochloric acid. By heating gypsum at successively higher temperatures four modifications can be prepared in order as follows: (1) the hemihydrate, CaSOd~H20, of which plaster of paris )The presence of anhydrite or gypsum in rock will influence the type of mud selected for drilling the rock because when CaSO 4 dissolves in a water mud, Ca +2 and SO 4 –2 ions are formed. Get article recommendations from ACS based on references in your Mendeley library. The temperature of the gypsum to anhydrite transition increases from 58 °C at 1 atm, to 63 °C at 493 atm (= 500 bar), and 70 °C at 987 atm (= 1,000 bar). Thermodynamic Modeling of Calcium Sulfate Hydrates in the CaSO4–H2O System from 273.15 to 473.15 K with Extension to 548.15 K. Teng Pan, Yan Liu, Wei Qin, Youwei Cheng, Lijun Wang. They add calcium ions (Ca 2+) and sulfate ions (SO 4 2-), but do not add or take away hydrogen ions (H +). You’ve supercharged your research process with ACS and Mendeley!
