The pH of a solution measures the amount of hydrogen ions that are in a solution. The term "pH" literally means "the power of hydrogen." The pH of a substance tells how acidic or basic a substance is. More »

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 »

Generally speaking, sugar is a pH-neutral substance, meaning that its pH value is around 7. However, raw and unprocessed sugar is slightly basic in nature, while white sugar and brown sugar are both slightly acidic. More » Health Medical Ranges & Levels

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 »
