pH 0-6.9

pH is simply the measure of how alkali or acidic a substance is through a scale of 0-14. Substances between 0-6.9 are acidic, 7 neutral and 7.1-14 is alkaline. Our hair and sebum naturally has a pH balance between 4.5 and 5.5.Apr 13, 2013

H 3 O +

the hydrogen ion bonded to a molecule of water, H 3 O +, the form in which hydrogen ions are found in aqueous solution. Expand. Also called oxonium ion. Origin of hydronium ion.

base

Any of a class of compounds that form hydroxyl ions (OH) when dissolved in water, and whose aqueous solutions react with acids to form salts. Bases turn red litmus paper blue and have a pH greater than 7. Their aqueous solutions have a bitter taste.

OH-

Hydroxide is a diatomic anion with chemical formula OH−. It consists of an oxygen and hydrogen atom held together by a covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water.

pH 7.9-143

In general, a water with a pH < 7 is considered acidic and with a pH > 7 is considered basic. The normal range for pH in surface water systems is 6.5 to 8.5 and for groundwater systems 6 to 8.5. ... In general, a water with a low pH (< 6.5) could be acidic, soft, and corrosive.

pH scale

Mixing acids and bases can cancel out or neutralize their extreme effects. 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.

H+

Science and technology. Electron hole, h+ the conceptual opposite of an electron. Evolved High Speed Packet Access, H+ mobile phone icon. Hydron (chemistry), H+ a cationic form of atomic hydrogen. Transhumanism, H+ is a symbol for Transhumanism.

pH 7

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. A pH less than 7 is acidic.

acid

a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind.
