What can magnesium metal be used for? | …
Magnesium is used in products that benefit from being lightweight, such as car seats, luggage, laptops, cameras and power tools. It is also added to molten iron and steel to remove sulfur. As magnesium ignites easily in air and burns with a bright light, it''s used in flares, fireworks and sparklers.
Magnesium | Elements | RSC Eduion
Fact file Atomic nuer 12; atomic mass 24.3050; melting point 649 C; boiling point 1090 C. Magnesium is in Group 2 of the Periodic Table (the Alkaline Earth Group). It is a light, silvery white, lustrous, soft metal when pure, with a density of 1.74 g cm-3 and it burns when ignited to form MgO and Mg 3 N 2.
Lab 8: Single Replacement Reactions - Chemistry Land
A more reactive metal, such as magnesium (or zinc) can sace itself by giving iron its electrons and forming magnesium hydroxide (magnesium corrodes instead of iron). So the single replacement reaction looks like this:

2020/3/24· Also known as the alkaline earth metals, group 2 consist of the elements Beryllium, Magnesium, Calcium, Strontium and Barium. They all have reasonably high melting and boiling points, low densities and they all form colourless compounds. Together with group 1
Determining Calcium Ion Concentration in Water …
Calcium and magnesium ions dissolved in water cause water hardness. Ethylenediaminetetraacetic acid (EDTA), shown on the right in its deprotonated form, is commonly used in a titration to determine the concentration of Ca 2+ and Mg 2+ ions in water because both ions form complexes with EDTA.
