Poisons are substances that cause a disturbance to organisms, most frequently through chemical reactions. Poisons are typically harmful, and cause damage or death to an organism.
Poisoning can result from many things, bites, plants, allergens, overdose of medicine, iodine, lead, food poisoning, etc.
Symptoms of poisoning include: dilated pupils, drooling, bleeding from orifices, change in skin color, increase in breathing and heart rate, nausea, diarrhea, fatigue, and headaches.
In our lab in school, we tested multiple unknown samples to see if they contained poison. We had different reagents and instructions, telling us what happens if they are a poison and how they would react.
Station One: Metals
1. Lead - Because it turned blood red when mixed with KSCN
2. Iron - Because it turned neon yellow when mixed with Potassium Iodide
3. Negative
Station Two: Sugars
All three were negative, none turned purple.
Station Three: Ammonia (pH greater then 7, strong odor and PHTH is purple/pink)
1. Postive odor, positive pH of 11, PHTH is purple/pink
2. Negative odor, positive pH of 8.5, PHTH is not purple/pink
3. Negative odor, positive pH of 8.5, PHTH is not purple/pink
Station Four: Aspirin (pH less than 7, BTB is yellow)
1. Positive pH of 5, BTB is not yellow
2. Positive pH of 6, BTB is not yellow
3. Positive pH of 2, BTB is yellow
Station Five: Cyanide (red with FE+3)
1. Does not turn red
2. Does not turn red
3. Did turn red
Station Six: Iodine (Blue with Starch)
1. Does not turn blue
2. Does not turn blue
3. Did turn blue
