INIT Summative Task 3 scientific discipline testation Colette Chamberland Western G everyplacenors University A. hurtle Plan I go away be conducting a science test on how different substances added to tap peeing exit imprint its boilers suit pH relief. We have it away that most substances are every shell or acerbic and I will stern my experiment on this. I will add substances that will veer the pH in any direction and entry these changes. trouble Statement I will measure how adding sodium bicarbonate, citric acid, calcium chloride and sodium carbonate affect the pH repose of tap body of water. I will use .5 ml of sound off tap water with nothing added to it only the universal index number liquid to get a baseline for the experiment. I will add .15 ml of each substance to the tap water to alter its pH balance. Relevance of testable question My experiment is grievous because a legal age of life requires water, and most of it requires the water to keep a particular(prenominal) pH range. Anything outside the normal ranges undeniable for specific life forms is typically detrimental and threatens its life over long periods of time. We know that many substances are either alkali or acid and affect the PH balance to either go up or down. The average pH for water is usually 7 but can be more or less(prenominal) higher or lower depending upon the water type and qua lighty. A2. lit Review Sara W., a student at Selah school did a mistakable experiment in 2002 for the Mid Columbia Regional wisdom Fair. She conducted her research on the pH levels of various popular daddy drinks. Her research was done using a pH meter, pH indicator, pH reference and the sodas that she would be examen the pH levels of. Her experiment is very similar as she was interrogatory a water based substance, which had additives that would modify its original pH balance. Her view concluded that different sodas have differen t pH levels based on the different ingredien! ts (Sara W., 2002). Another related field of honor was conducted in 2004 by another...If you want to get a robust essay, order it on our website: BestEssayCheap.com
