Chemical table of alkalinity and acidity ranging from 0 to 14. Less than 7 indicates acidity; 7 is neutral; more than 7 is alkaline.
A scale from 0 to 14 reflecting the concentration of hydrogen ions in solution; the lower numbers denote acidic conditions and the upper numbers denote basic, or alkaline, conditions.
The strength of acids and bases. Pure water has a pH value of 7, acids have a lower value and bases higher.
a measurement guide to acidity and alkalinity
The pH scale is used to measure the amount of acid in a substance. The lower the number, the higher the amount of acid. Rain below pH 5 is said to be "acid rain".
The scale, ranging from 0 to 14, used to measure the pH of a solution.
A scale graded from 0 (pure acid) to 14 (pure lye) used to measure acidity or alkalinity. From the neutral point (7.0) the numbers increase or decrease geometrically; thus pH 5 is 10 times more acid that pH 6; pH 4 is 100 times more acid.
A measurement of how acidic or basic a solution is. 41
a scale usually given as 0 to 14, in which a solution with a pH of 7 is neutral, 7 is acidic, and 7 is basic.
Scale marked from 1 to 14 measuring the hydrogen ion concentration, that is acidity or alkalinity of material. As per this scale, materials having pH less than 7 are acidic substances and above 7 are alkaline substances.
A logarithmic scale that is used to measure acidity; 1 is very acidic, 7 is neutral, and 14 is very basic (alkaline).
a way to show acidity and alkalinity on a scale of 0-14, with 7 representing neutrality. Numbers less than 7 indicate increasing acidity and numbers greater than 7 indicate increasing alkalinity.
This is a scale from 0 to 14. If the pH of a solution is 7 it is neutral; if the pH of a solution is less than 7 it is acidic; if the pH of a solution is greater than 7 it is basic.
A scale from 0 to 14 reflecting the concentration of hydrogen ions; the lower numbers denote acidic conditions, 7 is neutral, and the higher numbers denote basic (alkaline) conditions.
A scale used to determine the alkaline or acidic nature of a substance. The scale ranges from 1-14 with 1 being the most acidic and 14 the most basic. Pure water is neutral with a pH of 7.
A zero to fourteen scale that is used for expressing the exact degree of acidity or alkalinity of a solution. A pH of 7 signifies a neutral solution. Values below 7 signify an acid solution, and values above 7 signify an alkaline solution. e.g. pH of 2 is more acidic than a pH of 5. A pH of 12 is more basic than a pH of 9.
numerical system running from 0-14 and used to express the alkalinity or acidity of a chemical solution. 7 is neutral. Solutions with a lower pH value are increasingly acidic, and those with a higher pH value are increasingly alkaline
System for measuring the alkalinity or acidity of soil.
