Introduction
Being knowledgeable about what makes up a certain substance, and the concentration of it, can be very crucial in certain situations. An example of that, which applies to the environment and is very common, is the use of pesticides on various crops. Pesticides are essential to insure that crops are not contaminated by pests. Pests are destructive insects that attack crops, leading to diseases. Pesticide is a substance used to get rid of pests.
As a producer of the crop, it is very important to know what chemicals make up the pesticide, and its concentration. If the chemicals are too strong, or if the concentration is too high, then there would be a possibility of destroying the crop itself. On the other hand, if the chemicals in the pesticides are too weak, or if the concentration is too low, then there will not be the full …show more content…
In order to accomplish that, the titration lab was conducted. First, using a pipet, 10 ml of the base was placed into a volumetric flask. Next 6 drops of the pH indicator, was added into the base. After, the burette was filled up with the known acid, vinegar, up till 50 ml. Using the stopcock, the acid was slowly added to the base, after every few drops of the acid, the colour of the base would change into a green, and the base solution would get mixed. The same process was repeated, until the point, where the green colour did not disappear after the base solution was mixed, but instead the colour of the solution turned into a light green. Once the endpoint was reached, the volume of the acid used was recorded. Afterwards, the base was dumped into a sink, and the volumetric flask was cleaned. The entire process was recorded another two times, and the results were also recorded. Using the collected data from the lab and calculations, the concentration of the base was
