Andrew T. Hedrick Chem 32 Section S 10/11/02 Experiment 4 – The Alkaline Earths and the Halogens Purpose:  To study the properties of elements in two families, the alkaline earth  metals (Group IIA) and the halogens (Group VIIA). To understand oxidation- reduction reactions and relative strengths of oxidizing and reducing agents and  how these correlate to the trends on the periodic table of elements. Experimental Plan:  The instructions for this plan were based on The  Thompson  General Chemistry 2  Lab Manual, pages 69-73. The only change was that Part  IV was excluded from our tests. Data and Observations: Part I Ba(NO 3 ) 2 Ca(NO 3 ) 2 Mg(NO 3 ) 2 Sr(NO 3 ) 2 H 2 SO 4 sS milky sS tiny particles,  mostly clear S totally clear I participate in  bottom Na 2 CO 3 sS milky I milky, but very  thick I very thick milk I definate  precipitate  layer (NH 4 ) 2 C 2 O 4 I distinct layers  of solution
