7/9/2015 · The pH of the stomach can vary, between 1.5 and 3.5 on the pH scale. However, this has no effect on the pH of our body, or, more specifically, our blood. Human blood has a pH value that’s always slightly alkaline, between 7.35-7.45.
11/25/2014 · A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline(another way to say basic)than the.
6/15/2012 · The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14. It’s a lot easier to use a logarithmic scale instead of always having to write down all those zeros!
