Calculate the extent of change in pH obtained during the experiment. A4. This will partly depend upon the students results. For our graph the milk went through a change in pH of 1.95 (6.75 - 4.8). Q5. What do you think will be the result of incubating UHT milk over the same time period? A5.
The pH scale goes from 0-14 (with acidic substances falling below 7 and basic substances falling above 7). Normal levels for body fluid pH hover right in the middle of that range. Foods can either raise or lower your pH level, and this is based on the mineral content of the food â not the actual pH of the food itself. Lemon juice, for example, has a low pH, but has an alkalizing effect on the body when consumed.
