Magnesium Chloride
Magnesium Chloride is a strong, silvery white metal, lightweight (one-third lighter than aluminum) and will become dull if left on air. In the form of powder, this metal is very reactive and can burn with a white flame when the air is moist. When magnesium metal tape is burned and then immersed in water, it will remain burned until the magnesium tape is exhausted. Magnesium, when burned in air, produces bright white light. Industrial chemistry was used in the early days of photography as a source of lighting (lightning powder). The mass magnesium mass is 1,738 grams / cm3. The relative atomic mass is 24, and the atomic number 12. Magnesium melts at 111 ° C.
