Group 2 reactions, uses & solubility

• when you react metal with water vapor the metal becomes a metal oxide
• when a metal reacts with chlorine it produces a metal chloride
• when a metal reacts with oxygen it produces a metal oxide
• when a metal reacts with water it produces a metal hydroxide and hydrogen gas
• as you go down the group the solubility of metal hydroxides increases
• the use of magnesium hydroxide is that it can be used as a laxative and can be used as a indigestion remedy
• all group 2 nitrates and chlorides are soluble
• the solubility of group 2 metal sulfates are that they decrease down the group
• the use of barium meal is to allow doctors to examine the stomach, gut and esophagus through xrays
• barium sulfate is insoluble in water so is not harmful to digest
• magnesium hydroxide is insoluble so is not harmful to digest
