MAKE SOLUTION OF 5 g WASHING SODA (SODIUM CARBONATE) IN 50 ml WATER. ADD SOME OF THIS SOLUTION TO THE OTHER TWO. IN BOTH JARS YOU WILL GET A HEAVY WHITE PRECIPITATE. IN THE Mg JAR, THIS IS NORMAL MAGNESIUM CARBONATE (MgCOj). IN Zn JAR, CO, IS SET FREE AND BASIC ZINC CARBONATE (Zn OH),ZnCOj) RESULTS. [Pg.63]

When magnesium carbonate, MgCOj, is heated to a high temperamre, it decomposes. [Pg.482]

Dolomite is an alternative mineral that is used in some regions in place of cal-cite for certain applications. Dolomite is a calcium magnesium carbonate (CaCOj.MgCOj) and occurs widely in nature. Although generally similar to cal-cite in properties, it is shghtly harder (3.5), denser (2.85) and more acid resistant. Production is similar to that for calcite,but miUing is more costly and it tends to only be available at the coarser end of the size spectrum. [Pg.94]

Let s say you want to produce magnesium carbonate. The chart of solubilities on page 108 tells you that MgCOj is insoluble. You should therefore be able to precipitate it from a soluble magnesium salt — the sulfate, for instance — and soluble sodium carbonate ... [Pg.107]

The exothermic effects associated with some dehydrations [18] may result from delayed reciystallization, or the oxidation of a product of dehydration. Dehydration of magnesium carbonate trihydrate, followed by heating in carbon dioxide, resulted in the exothermic transformation of an anhydrous pseudomorph of the reactant into magnesite, MgCOj. [Pg.241]

DOLOMITE. CaMglCOjjj. Sp. gr. 2.9 hardness Mohs 3.5-4.0. Arock intermediate in composition between limestone (CaCOj) and magnesite (MgCOj). True dolomite is composed of 54% CaCOj and 46% MgCOj. Other materials containing appreciable amounts of magnesium carbonate, but less than the 46% found in true dolomite, are commonly called dolomitic limestones, and also are used in the ceramic industry. [Pg.754]

Magnesium (eighth most abundant element) is found principally as Mg+2 ion in salt deposits, particularly as the slightly soluble carbonate, MgC03, and also in sea water. The natural deposits of MgCOj with CaC02 are called dolomite. Magnesium is present as a cation in the asbestos silicates. [Pg.385]

Hardness due to calcium or magnesium ions, present as carbonates, is produced when shghdy acidic water trickles through limestone (CaCOj) or dolomite (CaCO -MgCOj). [Pg.243]

During natural deposition of carbonates, when magnesium salts are present, a mixture of magnesium and calcium carbonates are precipitated, which is known as dolomite. Dolomite contains about 40 to 45 % MgCOj and 55 to 60 % CaCOg. Its properties are close to those of natural calcium carbonate, except that it is slightly denser and less bright and less sensitive to acid than calcium carbonate. [Pg.193]
