Poison Analysis

       Poison is a substance that when it is absorbed by living organism it can be lethal. Some common poison sources are carbon monoxide, food poisoning,plants, household products, leads and medicines. In addition to poison can have an abundant of side effects such as enlarged pupils, drooling, change in skin colors, organ failure,and bleeding from any facial features. We did an experiment with using products such as metal poison, possible sugars,household ammonia,aspirin,and cyanide experiment to test if there were poison or not.

Poison Lab Pictures

    The first test we did was using metal poison.Metal poisoning is the accumulation of metals in the soft tissues of the body. This poisoning can be lethal.First we tested the lead (Pb). When KI is added to these chemicals, lead should turn to a yellow precipitate if it is a metal poison. When we tested lead with .5m KSCN is was negative. When we tested lead with KI, it was positive for lead . When we tested lead (Pb) with acid, it turned out to be negative. So no yellow precipitate was shown for KSCN and using the acid it did not turn yellow.  When KI was added with lead it turned yellow so it is a metal poison.   The second chemical we used was Iron (Fe). When KSCN is added it should turn to a blood red. If it turns to a bloody red, then it is metal poisoning. When my group tested iron with .5m KSCN it was positive for metal poisoning it turned bloody red. So that means it could be a metal poison. When we tested KI with iron it turned out to be negative . When we tested the acid with iron it also turned out negative to be a metal poison. The third trial we used the chemical chromium. chromium is a metal poison only if it is orange when acidified. When we added the .5m KSCN with the chromium it turned out to be negative for metal poison. When we used KI  added to chromium it turned out to be negative for metal poison.



Possible sugars

                                                                                                         

When sugar test reagent is added, a purple color will form.       




1. The first test it turned out to be negative.There was no purple color.
2. The same test results.
3. The same test results.

Household ammonia

Household Ammonia       


      To see if household ammonia was a metal the results had to have three rules. The first rule was it must have odor. The second rule was the ph had to be above seven. The third rule was the phth is pink or purple in the solution.These are our test results.The first household ammonia was positive. It had the odor , the ph was above seven and the phth is pink or purple in the solution.The other two household ammonia tested negative. These trials did not meet the criteria for being a poison.






Aspirin

   This experiment has two rules also in order for it to be considered a poison. The ph is below 7 and the BTB is yellow. The first trial with aspirin passed the test. It had a ph of 3 and the BTB turned yellow. The other two trials of aspirin however did not pass the test to be considered a poison.





Cyanide Experiment
This experiment requires only  one rule to be considered a poison. If the result turns blood red when Fe +3 is added, then it is considered a poison. The first and third result however did not turn a bloody red but the second trial did turn out to be cyanide which was a poison.



Through these experiments I learned a lot about poison. I've always knew poison could kill you. I  did not know what kinds of poisons there are. Everybody knows bleach is a poison.I really did not know how to test to see if it was really a poison. It is important to know these certain poisons to save your life. I did not know that house hold ammonia  could be a metal poisoning either.
