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. More »

Red cabbage juice is a good indicator of pH because it contains flavin, a pigment molecule that changes colors according to the concentration of hydrogen ions in a solution. The juice is prepared by soaking chopped red c... More »

By definition, pH is a measure of the hydrogen ions in an aqueous solution. As table salt, in its pure form, is not dissolved in water, it has no pH. More »

In chemistry, the main difference between pH and pKa is that pH tells the level of hydrogen ions in a certain medium while pKa value indicates the degree at which an acid dissociates or the side at which equilibrium is f... More »

A solution with a pH of 3 is considered acidic. It is roughly the same level of acidity as lemonade or an apple, according to the U.S. Environmental Protection Agency. More »
