Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2. ... These compounds are mainly used for de-icing and dust control.
A small percentage of owners of indoor arenas (for example, for horse riding) may apply magnesium chloride to sand or other "footing" materials to control dust. Although magnesium chloride used in an equestrian (horse) arena environment is generally referred to as a dust suppressant it is technically more accurate to consider it as a water ...
Aqueous lignosulfonate solutions are also widely used as a non-toxic dust suppression agent for unpaved road surfaces, where it is popularly, if erroneously, called "tree sap". Roads treated with lignosulfonates can be distinguished from those treated with calcium chloride by color: lignosulfonates give the road surface a dark grey color, while ...
Other common desiccants include activated charcoal, calcium sulfate, calcium chloride, and molecular sieves (typically, zeolites). Desiccants may also be categorized by their type, either I, II, III, IV, or V. These types are a function of the shape of the desiccant's moisture sorption isotherm. Alcohols and acetones are also dehydrating agents.
Calcium chloride is also used to reclaim alkali soils. CaCl 2 converts Na 2 CO 3 into NaCl precipitating CaCO 3. NaCl is drained off by leaching water. Calcium nitrate has a similar effect, with NaNO 3 in the leachate. Spent acid (HCl, H 2 SO 4, etc.) can also be used to reduce the excess Na 2 CO 3 in the soil/water.
Startled awake, mom discovers her son is shot. As Givens snapped awake, her son Destin was screaming, his right hand bleeding. Givens’ .22-caliber Glock handgun lay on the floor nearby.
Dust abatement refers to the process of inhibiting the creation of excess soil dust, a pollutant that contributes to excess levels of particulate matter. Frequently employed by local governments of arid climates such as those in the Southwest United States , dust abatement procedures may also be required in private construction as a condition ...
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
