Finding the PH of different concentrations of orange juice. Research Question
By diluting concentrated orange juice with water, can you significantly change the PH value?
Introduction
Across the world, it is thought and widely accepted to believe that Orange juice is the cure to many terrible diseases. However, this may not be true anymore. It has been said that Oranges are very high in vitamin C, therefore one should drink it every morning to stay healthy and prevent the symptoms of any diseases. Oranges apparently are “too acidic to justify the worth of drinking every morning for the miniscule amounts of vitamin C it contains” (Dr. Kenny and Henderson). It has been found that orange juice, while it does contain vitamin C, does not contain enough vitamin C to live up to the “super food” standard that was set for it in the past. Instead of assisting one’s immune system, it has now been discovered that due to the naturally high acidity of orange juice, they actually are detrimental to ones health. Drinking orange juice every day will eventually cause many issues, including stomach ulcers. These painful issues are very real dangers, especially when one has been taught throughout their life to drink orange juice every morning. However, if the pH of the orange juice is decreased, the effects the acidity will have on ones body will be exponentially decreased. The purpose of this experiment is to see if one could simply water down their morning glass of orange juice to protect their health, and continue their habits.
Hypothesis
If the change of pH in orange juice is tested with concentration, then the more water added to dilute the orange juice, the closer the pH will be to seven, because the pH of water is seven, so if the solution were to get infinitely close to pure water, the pH would become seven.
Procedures
1. Make sure to have safety garments and gear on, goggles and aprons, before starting the
