White Grape Juice made from concentrate gives a pH of around 2 - 2.1.
This would be more acidic than Orange Juice. someone please fix this.
I tested it today in lab class, it seems a lot but the White Grape juice we had had a pH of about 2.
The pH level for grapefruit juice is between 3 - 3.3
The pH level of grapefruit typically ranges from 3.0 to 3.3, making it acidic.
2.3

there is pretty much no acidity in a grapefruit...it is only bitterness.
Vinegar is more acidic than grapefruit juice. Vinegar typically has a pH of around 2.4 to 3.4 due to its acetic acid content, while grapefruit juice has a pH of about 3.0 to 3.8, primarily from citric acid. Therefore, vinegar is generally considered to be more acidic than grapefruit juice.
Acid-- it has a ph of less than 7.
Lemon has a higher concentration of Citric acid that is why it is more sour.
a lemon is more sour than a grapefruit because it is more acidic.
I think it would be either a lemon a grapefruit (the yellow grapefruit is the most sour).
The pH of grapefruit by itself is low enough to prevent the growth of pathogens. What we don't know is the pH of the jarred product and if there has been any cross-contamination. For quality purposes, keep the opened jar refrigerated and use it within a few days.
I think they are both citric acid but lemon juice is more concentrated.
