These examples are programmatically compiled from various online sources to illustrate current usage of the word 'magnesium carbonate.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Jacqueline Detwiler-George, Popular Mechanics, 16 Mar. 2010 FrictionLabs's chunky and fine chalks contain purer magnesium carbonate than other chalks. Lindsey Konkel, Discover Magazine, 9 Feb. Hard water may also react with other substances in the solution, such as soap, and form a precipitate called 'scum. In this study, adopting a novel wetted wall. Whereas previous studies have focused on testing reactive crystallization and precipitation kinetics, much less attention has been paid to absorption, the key process determining the removal efficiency of CO2. 2022 The formation consists of peridotite, a rock containing minerals that react with CO2 to form solid magnesium carbonate. This displacement of minerals from the solution is responsible for the calcination often seen on water faucets, which is a precipitation of calcium or magnesium carbonate. CO2 absorption and carbonate precipitation are the two core processes controlling the reaction rate and path of CO2 mineral sequestration. Amber Smith, Discover Magazine, 11 Oct. The green flame shows that Cu 2+ ions are present, and the white precipitate of silver chloride shows that Cl-ions are present. 2023 The powder contains only magnesium (as magnesium carbonate), with a potency of 325 mg per 4 grams of powder. Renee Freemon Mulvihill, Better Homes & Gardens, 14 Feb.
2010 Limestone in the mix keeps the pH neutral (ideal conditions for the majority of plants), thanks to a blend of calcium carbonate, and magnesium carbonate. The precipitation of different forms of magnesium carbonate has been studied at temperatures between 25 and 120C and at a partial pressure of CO2 between 1 and 100bar. Using a 1.0 mL syringe inserted through the septum add 0.5 mL of anhydrous diethyl ether to the reaction vessel. Weigh magnesium powder (50 mg, 2 mmol) and add it to your reaction vessel. Lindsey Konkel, Discover Magazine, 9 Feb. Obtain 3 mL of anhydrous diethyl ether from your GSI in one of the oven dried dram vials. 2012 Normally, the reaction happens too slowly to be useful, but injecting carbon dioxide into the rock at high pressure would speed things up considerably the formation of magnesium carbonate could cause the rock to expand and crack, with the increased surface area spurring the reaction to continue. Douglas Fox, Scientific American, 1 July 2021 There, in a 33.5 meter tower, a CO2-rich flue gas mixed with seawater droplets to form the calcium and magnesium carbonates that would be the stuff of cement. Willow Jarosh, Ms, Rd, Health, 27 June 2023 The results suggested that as rain soaks into cracks in the ground, CO2 dissolved in the rainwater pairs up with magnesium atoms, forming magnesium carbonate veins, until the small amount of gas in the water quickly runs out. Recent Examples on the Web While both the carbonate and chelated forms of magnesium can boost your magnesium level, note that magnesium carbonate may have a laxative effect.
