Welch Ph Lab

1. The pH of Welch’s Juice Significantly different than what I had hypothesized. I reject that part of my hypothesis because I feel like it was too far from what the actual number was. I had hypothesized 6 because I felt like the other parts of that solution would make it less acidic. I was wrong and the actual number was 3. On the other solutions I was exactly on or off by one number.
2. The pH range of my solutions were from 2.5-7.The most acidic solution I had was vinegar which had a pH of 2.5. I did not have any bases in the solutions I had tested. I did have 1 neutral.
3. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. In our way of measuring for the pH scale I would consider the pH scale as relative, but I know that there are ways to get an exact way to find the number. So, I believe for our experiment it was a relative measure. …show more content…
If p in pH stands for the German word Potenz,, which means “power’ or “potential” and the H represents hydrogen ions, the two terms are related to the definition because the pH scale shows the amount of power the hydrogen has in the pH scale.
5. The relationship between the hydrogen ions and pH is that the more hydrogen ions, the lower the pH value of the solution. The pH is related to the acidity because acidity is a measure on
