Magnesium carbonate, Mg CO3 (archaic name magnesia alba), is an inorganic salt that is a white solid.Several hydrated and basic forms of magnesium carbonate also exist as minerals.orms [edit]. The most common magnesium carbonate forms are the anhydrous salt called magnesite (MgCO 3) and the di, tri, and pentahydrates known as barringtonite (MgCO 3 Â·2 H 2 O), nesquehonite (MgCO 3 Â·3 H 2 O), and lansfordite (MgCO 3 Â·5 H 2 O), respectively.
Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  When treated with HBr or HCl alcohols typically undergo a nucleophilic substitution reaction to generate an alkyl halide and water.eaction of Alcohols with other Halogenating agents (SOCl2, PX3). Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  Alcohols can also be converted to alkyl chlorides using thionyl chloride, SOCl2, or phosphorous trichloride, PCl3.
Remind students that isopropyl alcohol has an oxygen atom bonded to a hydrogen atom so it does have some polarity but not as much as water. Since water is more polar than alcohol, it attracts the positive sodium and negative chloride ions better than alcohol. This is why water dissolves more salt than alcohol does. Another way of saying this is that the solubility of salt is greater in water than in alcohol.
