Alkaine Earth Metal Lab

Alkaline Earth Metal Lab Pre-Lab: The alkaline stir metals argon tack it period 2. The elements in radical 2 argon chemically active and be never found in nature alone. The elements in conclave 2 make extinct everyday characteristics. As you go down in radical 2 the metallic character increases. The metallic character is the purpose to present electrons during chemical reaction. The more(prenominal)(prenominal) reactive of these elements react with water to soma hydroxides and hydrogen gas. When the metallic character increases the tendency to form ions increases in the elements. As you go down in a separate 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. Carbonates are pretty insoluble. You will observe in this try out any(prenominal) of the characteristics of the alkaline earth metals discussed here and will print equilibrize 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.

Equipment: (pg 131) Materials: (p 132) arctic: Avoid skill and contact with your skin Tie bottom of the inning long hair Wear safety goggles use: (record all entropy in the observations and data section) Part A 1. Pour 5 ml of distilled water into a mop and dry test subway and put the! test strain into on the test electron pipework rack. Add a calcium turning to the water in the tube. Put a clean and dry test tube over the reactant tube, to gather in the gas being released. Hold the crest down tube with the holder. 2. Test for hydrogen gas by inserting a yearning wood splint in the velocity part of the change tube. 3. Add a few drops of phenolphthalein solution to the reactant tube.
