The pH and/or acidity of a many soups, homemade or commercial is presented below. The term "pH" is a measure of acidity; the lower its value, the more acid the food. The equipment used for determining pH was generally pH meters.

In using this table, bear in mind that considerable variation exists between brands, varieties, recipes, formulations and processing methods, etc.  Where the research found a range of values due to variability in the samples, the range is provided.  Where a single consistent value was determined, that value is provided.
