Hard water boiling. When this is the case, it is usually caused by the presence of calcium sulphate/calcium chloride and/or magnesium sulphate/magnesium chloride in the water, which do not precipitate out as the temperature increases. Ions causing permanent hardness of water can be removed using a water softener, or ion exchange column. Total Permanent Hardness = Permanent Calcium Hardness + Permanent Magnesium Hardness With hard water, soap solutions form a white precipitate (soap scum) instead of producing lather, because the 2+ ions destroy the surfactant properties of the soap by forming a solid precipitate (the soap scum). A major component of such
Magnesium acetate LiCl, MgSO and MgCl were all compared to see what effect they had on the "Escherichia coli" enzyme Primase. The experimenters found that Mg(OAc) caused the best conformational change. MgSO and MgCl induced the effect slightly while the rest did not. When magnesium acetate is mixed with hydrogen peroxide it acts as a bactericidal. Magnesium acetate has been shown to be effective at ashing organic compounds in preparation for a fluorine analysis when high or low concentrations of fluorine are present. Magnesium acetate is a relatively safe compound to handle and has been given a health hazard rating of zero.
