Introduction to cyanide In Ms. Chien's class at SOF, we did a series of tests on the water of schools. We were supposed to find out if the water had cyanide in it and how much of it too. Our compound is mostly found in power plants and factories. It is a pollutant and can be very dangerous. We think that none of the school waters have any cyanide in it. Not even a little.
	Materials: For this experiment, we used... 1.10ml of our water sample. 2. 2 drops of the cyanide testing solution #1 3. 2 drops of cyanide testing solution #2 4. one eyedropper 5. small measuring spatula 6. various beakers for measuring
Rusults: school negative positive SOF Ã PS.234 Ã 104 Ã 131 Ã 11 Ã	These are most of the results we placed down because every school does not have cyanide in the water.  There is a root in developing countries called the cassava. If not prepared properly, the root can have high levels of cyanide in it. Symptoms of it are wrecked nerves, and pregnancy problems. The list of symptoms is long. Another supplier of cyanide are power plants.
Procedure: #1. Measure a 10 ML water sample into the calibrated tube #2. Add 2 drops of cyanide test 1 and mix #3. Add 2 drops of cyanide test 2 and mix #4. If cyanide is present, a pink color will develop which turns violet in a few minutes. Allow approximately 10 minutes for the color to develop.

Discussion: Our results say our school does have cyanide in its drinking water, and from the result table it shows that it was the same with other schools. Looking back on our hypothesis, we see that we are right because, there was a cyanide contamination, then the whole city would be in a state of jeopardy! Our ideas on preventing a problem like this would be that we must have power plants farther away from the water supply because if they are near by then they will totally pollute the water and have people having horrible illness's. There seems to be no pros on cyanide because it hurts the nervous system especially. It can cause extreme reactions and also cause birth defects with the unborn child. (if a mom is carrying one.) This topic can also connect to ammonia and chlorine because they clean the water and can help prevent cyanide in it.
