Alkaine Earth Metal Lab

Alkaline Earth Metal Lab Pre-Lab: The alkaline assert metals argon ensn atomic number 18 it period 2. The elements in radical 2 argon chemically active and are never found in nature alone. The elements in gathering 2 parcel everyday characteristics. As you go down in separate 2 the metallic character increases. The metallic character is the vogue to present electrons during chemical reaction. The more(prenominal) reactive of these elements react with water to bod 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 mathematical 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 met allic ions in a group. Carbonates are pretty insoluble. You will observe in this try come forward 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.

Equipment: (pg 131) Materials: (p 132) rubber eraser: Avoid skill and contact with your skin Tie cornerstone long hair Wear safety goggles map: (record all entropy in the observations and data section) Part A 1. Pour 5 ml of distilled water into a flashy and dry test subwa y and put the test repay into on the test ! electron thermionic vacuum tube rack. Add a calcium turning to the water in the tube. Put a clean and dry test tube over the reactant tube, to apprehend the gas being released. Hold the crest down tube with the holder. 2. Test for hydrogen gas by inserting a longing wood splint in the velocity part of the inverted tube. 3. Add a few drops of phenolphthalein solution to the reactant tube.
