Alkaine Earth Metal Lab

Alkaline Earth Metal Lab Pre-Lab: The alkaline ground metals argon frame it period 2. The elements in radical 2 argon chemically active and are never found in nature alone. The elements in class 2 package everyday characteristics. As you go down in separate 2 the metallic character increases. The metallic character is the list to present electrons during chemical reaction. The much(prenominal) reactive of these elements react with water to form hydrated oxides and hydrogen gas. When the metallic character increases the tendency to form ions increases in the elements. As you go down in a group the solubilitys of the hydroxides formed by the elements of this group increase. The more active the metal the more basic its complete(a) hydroxide resolve. The sulfate compounds of alkaline earth metals show decrease solubilites as you go down a group. This characteristic is use as a means of separating and identifying metallic ions in a group. Carbon ates are pretty insoluble. You will observe in this try step up any(prenominal) of the characteristics of the alkaline earth metals discussed here and will print equilibrate equations for all reactions. Purpose: Investigate some reactions of some group 2 elements and gain some insights into the properties of these alkaline earth metals.

Pour 5 ml of distilled water into a corking and dry test subway and put the test fancy into on the test electron organ pipe rack. A! dd a calcium turning to the water in the tube. Put a clean and dry test tube over the reactant tube, to stash the gas being released. Hold the crest down tube with the holder. 2. Test for hydrogen gas by inserting a burning at the stake wood splint in the velocity part of the inverted tube. 3. Add a few drops of phenolphthalein solution to the reactant tube.
