Physical properties calcium chloride

Barium is a member of the aLkaline-earth group of elements in Group 2 (IIA) of the period table. Calcium [7440-70-2], Ca, strontium [7440-24-6], Sr, and barium form a closely aUied series in which the chemical and physical properties of the elements and thek compounds vary systematically with increa sing size, the ionic and electropositive nature being greatest for barium (see Calcium AND CALCIUM ALLOYS Calcium compounds Strontium and STRONTIUM compounds). As size increases, hydration tendencies of the crystalline salts increase solubiUties of sulfates, nitrates, chlorides, etc, decrease (except duorides) solubiUties of haUdes in ethanol decrease thermal stabiUties of carbonates, nitrates, and peroxides increase and the rates of reaction of the metals with hydrogen increase.

Chemical treatment of natural waters. Both directly and indirectly, the general problem of purification and treatment of natural waters is related to the chemical and physical properties of the normal and acid salts of carbonic acid. The common impurities in natural waters consist of suspended solid organic and inorganic materials and of certain dissolved salts, particularly the acid carbonates, chlorides, and sulfates of sodium, calcium, and magnesium. The solid matter may be removed by filtration, the presence of limited quantities of sodium salts is not objectionable, and the calcium and magnesium salts are eliminated only through appropriate chemical treatment. The ions that are most... 

Columns of calcium alginate gel pellets have excellent physical properties when used as supports for cell immobilization. Saccharomyces uvarum cells have been mixed with high concentrations of sodium alginate, precipitated by addition of calcium chloride, and extruded as discrete droplets which were found to be very resistant to compression and abrasion during passage of high concentrations of sucrose at high flow rate. 

The orange-red solid is moisture sensitive and should be handled in a glove bag and stored in a Teflon -stoppered flask under nitrogen. For long-term storage, the flask should be kept in a desiccator containing calcium chloride. The solid gives dark red solutions when soluble 1,1,1-trichloroethane (soluble), 1,2-dichloro-ethane (soluble), toluene (low solubility), dichloromethane (insoluble), and o-dichlorobenzene (insoluble). The physical properties have been reviewed. ...
