 (Mg) [mag-ne´ze-um]
a chemical element, atomic number 12, atomic weight 24.312. (See Appendix 6.) Its salts are essential in nutrition, being required for the activity of many enzymes, especially those concerned with oxidative phosphorylation. It is found in the intra- and extracellular fluids and is excreted in urine and feces. The normal serum level is approximately 2 mEq/L. Magnesium deficiency causes irritability of the nervous system with tetany, vasodilation, convulsions, tremors, depression, and psychotic behavior.
Homeostasis of magnesium in extracellular fluids. The normal serum magnesium level is regulated by intestinal and renal function. Most of the body's magnesium is stored in bones, muscle, and soft tissue. From Malarkey and McMorrow, 2000.

magnesium chloride an electrolyte replenisher and a pharmaceutic necessity for hemodialysis and peritoneal dialysis fluids.
magnesium citrate a saline laxative used for bowel evacuation before diagnostic procedures or surgery of the colon; administered orally.
magnesium hydroxide an antacid and cathartic.
magnesium oxide an antacid and a sorbent in pharmaceutical preparations; called also magnesia.

As the treatment continued, nesquehonite formation was further reinforced and spread over a larger percentage area of each sample; the crystals grew in length and were more visible with clear boundaries.
The performance a sample 3 confirms that the short treatment time of 15 min, which enables only a limited percentage of nesquehonite formation, was sufficient to prevent blister formation on the samples and resist corrosion over the 300 min time frame.
Based on these data, it was confirmed that the presence of both Mg and nesquehonite are required for optimal corrosion protection.
