What are some substances that are neutral?
The neutral substances that are the most well known are: water, table salt, sugar solution and cooking oil. We have learnt about three classes of substances: acids, bases and neutral substances. But, we cannot tell whether a substance is an acid, base, or a neutral substance, just by looking at it.
A substance that is neither acidic nor basic is neutral. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral.
- pH stands for power of hydrogen, which is a measurement of the hydrogen ion concentration in the body. The total pH scale ranges from 1 to 14, with 7 considered to be neutral. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline.
- The pH of healthy skin is between 4.5 and 5.5. Traditional soap is generally at about a 9, which is far too alkaline. Even "pH balanced" soaps, including Dove, are generally at a 7, which is neutral, but still too alkaline to be truly good for skin.
- PH meter. PH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode.
