The alkaline earths and the halogens two

Search The Alkaline Earths and the Halogens: Two Families in the Periodic Table Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide.

Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.

View pages 25-28 in the lab Manuel. In part c of the experiment we were asked to list the 4 alkaline earth metals in the order which they should appear in group 2 of the periodic table based on our observations.

  1. When a solution of A is mixed with one containing B ions, the color remains green.
  2. I came to the conclusion that they should appear Cl, Br, I from top to bottom respectively. Using this information it made sense to react my unknown 8 halide with Cl2.
  3. Use the other side of this page.

I came the conclusion that they should appear as Mg, Ca, Sr, Ba from top to bottom respectively. I came to this conclusion since I know mass increases from top to bottom of the periodic table and the reactions with more precipitate and color would have a greater mass.

Also we were asked to find the proper ordering in the periodic table of the given halogens based on our observations. I came to the conclusion that they should appear Cl, Br, I from top to bottom respectively.

Based on the previous information regarding mass increases as you go down the periodic table I was able to come to this conclusion.

  1. Using this knowledge I came to the conclusion that my unknown 8 halide is Cl-.
  2. I came to the conclusion that they should appear Cl, Br, I from top to bottom respectively. In solution, A is green, B is yellow, is red.
  3. Is A a better oxidizing agent than B? Search The Alkaline Earths and the Halogens.
  4. Substances A, B, and C can all act as oxidizing agents. The Alkaline Earths and the Halogens All of the common noble gases are monatomic and low-boiling.
  5. Ne, 245; Ar, 186; Kr, 152; Xe, 107. The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide.

I observed that Cl had the least color concentration, then Br, then I had the most. The greater the color concentration, the greater the mass.

The Alkaline Earths and the Halogens: Two Families in the Periodic Table

This observed data let me come to my conclusion. I did this experiment and the reactant was milky white. Based on this reaction in comparison to my previous reactions I concluded that unknown 8 alkaline was the alkaline earth Ba.

  • Is A a better oxidizing agent than B?
  • Two Families in the Periodic Table Introduction;
  • I came to this conclusion since I know mass increases from top to bottom of the periodic table and the reactions with more precipitate and color would have a greater mass;
  • The greater the color concentration, the greater the mass;
  • The Nat ion is effectively inert.

This experiment was most efficient because it only took one step to figure out what my unknown was, since their was four different reaction outcomes and four different earth metal each matching to one out come this was clearly the most efficient way. To find the unknown 8 halide I realized that the Halogen Cl2 had three distinct reactions for each halide.

Using this information it made sense to react my unknown 8 halide with Cl2. Using this knowledge I came to the conclusion that my unknown 8 halide is Cl.

I came the conclusion that Alkaline Earths should appear as Mg, Ca, Sr, Ba from top to bottom respectively in the periodic table. I also concluded that Halogens should appear Cl, Br, I from top to bottom respectively in the periodic table.
