How acedic is white vineger?

The acidity of white vinegar is typically measured in terms of its acetic acid content. Most white vinegars sold for household use have an acetic acid content of around 5%, which gives them a pH level of around 2.4. This means that white vinegar is a moderately strong acid, with a pH level closer to battery acid (approximately 0 pH) than pure water (7 pH). However, it is still much less acidic than stomach acid, which has a pH level of around 1.5-2.
