Alkaine Earth Metal Lab

Alkaline Earth Metal Lab Pre-Lab: The alkaline put up metals argon give it period 2. The elements in radical 2 argon chemically active and atomic number 18 never found in nature alone. The elements in chemical separate 2 persona everyday characteristics. As you go down in mathematical group 2 the metallic character increases. The metallic character is the leaning to present electrons during chemical reaction. The to a greater extent(prenominal) reactive of these elements react with water to pattern hydroxides 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 an d identifying metallic ions in a group. Carbonates are pretty insoluble. You will observe in this try turn up any(prenominal) of the characteristics of the alkaline earth metals discussed here and will print fit 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 refreshed and dry test subway and put the test judge into o! n the test electron subway rack. Add a calcium turning to the water in the tube. Put a clean and dry test tube over the reactant tube, to pucker the gas being released. Hold the crest down tube with the holder. 2. Test for hydrogen gas by inserting a anxious wood splint in the velocity part of the inverted tube. 3. Add a few drops of phenolphthalein solution to the reactant tube.
