The pH level of a substance describes how acidic or basic it is. Substances with a higher pH level are more basic, while substances with a lower pH level are more acidic. A substance with a pH of 7 is considered neutral, neither acidic nor basic.


A good pH level depends on the substance in question. Some substances are meant to be more acidic and others more basic, while some substances should be neutral. For instance, stomach acid has a pH of 1, while pancreatic secretions are basic with a pH of 8.1.


The pH of hydrochloric acid is 0. This reading is taken from a solution of 1 mole of hydrochloric acid. A less concentrated solution of the acid, such as a 0.5-mole solution, has a higher pH, meaning it would be less acidic.


According to the Pennsylvania Department of Conservation and Natural Resources (DCNR), changes in water's pH levels are caused by the dumping of certain chemicals into water systems. Dumping may be done by communities, industries or individuals.


The pH level of sugar is 7 because sugar is neutral. The pH of any substance that is neither an acid nor base is 7.


In its natural form, salt does not have a pH balance. A pH balance is only used with solutions that are liquid based. The term pH refers to the hydrogen levels in a solution, which is what affects a solution's acidic/alkaline levels.


To find the pH of a solution, calculate the concentration of hydronium ions present in the solution. Water dissociates into a hydronium ion and hydrogen oxide. The pH level can be calculated using the expression pH= -log (H3O).


Some pH levels of common substances include a pH of 7.0 for pure water, a pH of 2.0 for lemon juice and a pH of 11.0 for ammonia. Human blood has a pH of 7.4, tomatoes have a pH of 6.6, and vinegar has a pH of 2.2.


Some pH levels of common fruits include Delicious apples (pH 3.9), bananas (pH 4.5 to 5.2), cantaloupe (pH 6.13 to 6.58), oranges (pH 3.69 to 4.34) and strawberries pH 3.0 to 3.9). The pH of fresh peaches is 3.3 to 4.05, while for canned peaches it ranges from 3.7 to 4.2. Fruits with a pH of 4.6 and


The pH level of milk is about 6. In comparison, water's pH level is 7. That is a significant difference because each level is 10 times different --either more or less-- than the level next to it.
