KCl*MgCl₂*6H₂O– carnallite

_{Physical properties}

Magnesium is a shiny, silver or gray colored metal that is light inweight and strong. Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight. Chemical Properties: Magnesium is a silvery whitemetal.

Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium's melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

Chemical properties

Flame test:

Mg: White

Ca: Dark red

Burns with a bright white flame to give a white product (Magnesium oxide)

2Mg +O₂→2MgO

Burns with a bright white flame giving a white product (Magnesium chloride)

Mg +Cl₂→MgCl₂

Magnesium reacts slowly with cold water, forming magnesium hydroxide and bubbles of hydrogen:

Mg +2H₂O →Mg(OH)₂+H₂

It reacts vigorously if steam is passed over the heated metal, forming magnesium oxide and hydrogen:
Mg +H₂O →MgO +H₂
Magnesium. Slight reaction. pH=9
