Magnesium chloride.hexahydrate

In preparation of MgCl2 from seawater, magnesium hydroxide, Mg(OH)2, is first precipitated from seawater by the addition of dolime or lime. This is then treated with hydrochloric acid to produce a neutralized magnesium chloride solution. The solution obtained is evaporated and converted into soHd magnesium chloride hexahydrate (60,61). 

Dithioglycerol is prepared in the following manner 1,537 parts of sodium monosulfide nonahydrate and 411 parts of powdered sulfur are dissolved with stirring in 1,345 parts of water. Magnesium hydroxide is precipitated in the stirred sodium trisulfide solution by adding successively 97 parts of sodium hydroxide dissolved in 180 parts of water and then slowly 246 parts of magnesium chloride hexahydrate dissolved in 180 parts of water. The... 

Treatment of nitriles with gaseous hydrogen sulfide in the presence of anion exchange resin (Dowex 1X8, SH from) at room temperature affords the corresponding primary thioamides.27 Treatment of nitriles with 70% sodium hydrosulfide hydrate and magnesium chloride hexahydrate in DMF or methanol affords primary thioamides in high yields.28 Primary thioamides have been...

Put a small amount of the magnesium chloride hexahydrate into a crucible and roast it. What is observed Decompose the salt completely. How can you see that this has occurred Cool the crucible and add 1-2 ml of water. What is the composition of the substance that has not dissolved in the water ... 

Preparation of Anhydrous Magnesium Chloride, a. Thoroughly stir magnesium chloride hexahydrate with ammonium chloride, (take the substances in a proportion of 1 2 by mass, respectively), put the mixture into a crucible, and roast it in the flame of a gas burner. Cool the crucible in a desiccator (why ).

Magnesia mixture (0 5m for magnesium). Dissolve 102 g magnesium chloride hexahydrate, MgCl2.6H20, and 107 g ammonium chloride, NH4C1, in water, dilute to 500 ml, add 50 ml concentrated ammonia and dilute the solution to 1 litre with water. 

Dissolve 0.304 g of anhydrous calcium chloride and 0.139 g of magnesium chloride hexahydrate in distilled water and make up to 1 litre. This provides water with a hardness of 342mg/l, calculated as calcium carbonate.

The bittern (spent brine) from solar salt production contains 300 00 g/L dissolved solids relatively enriched in the less concentrated salt impurities. This may be either discarded or further worked to recover other elements of value. Brine from the Great Salt Lake, for instance, is processed for magnesium chloride hexahydrate recovery [10], which occurs at a density of 1.26g/cm. This is later converted to metallic magnesium [12]. The Dead Sea brines are processed primarily for potassium chloride (potash), but are also worked for sodium and magnesium chlorides and derived products such as bromine and hydrochloric acid [16] (Sections 6.2.2 and 8.8). 

EDTA solution approx. 0.01 (N) Dissolve 2.0 g disodium dihydrogen ethylenediamine tetraacetate (Na2 H2 CjoH 2 8 2 2H2O) and 0.05 g magnesium chloride hexahydrate in one litre water and standardize against standard calcium solution. 

If the EDTA solution is prepared by dissolving 2.0 g of the salt in one litre water without addition of 0.05 g magnesium chloride hexahydrate, then use calcon indicator during standardization of EDTA with standard calcium solution.
