pH is the measure of the acidity or alkalinity pH means the power of Hydrogen. It is 'minus the decimal logarithm of the hydrogen ion activity in an aqueous solution'. The term was coined by Sørensen, it measures the alkalinity or acidity of a liquid. pH is a measure of the concentration of hydrogen ions [H+] in a solution. The concentration of the hydrogen ions is measured in Molarity (M), or moles of H+ ions per liter of solution. The pH is then expressed as the negative log (base ten) of the hydrogen ion concentration. pH = -log[H+] For example, if a solution has a hydrogen ion concentration of 4.75 x 10-5 M (or 4.75 x 10-5 moles of H+ ions per liter of solution), then the pH of the solution would be -log[4.75 x 10-5] = 4.323 pH is generally given on a scale from 0-14, with 0 being the most acidic solution (like HCl) and 14 being the most basic solution (for example, NaOH.), although extreme values may sometimes fall outside that range. Pure water has a pH of 7 because its H+ concentration is 1.0 x 10-7 M -log[1.0 x 10-7] = 7
The mathematical term for "mean" is "mean".The popular, or colloquial term for "mean" is "average".
If by pH you mean the acidity of a compound then by combining equal amounts of each pH they would all "cancel each other out" i.e. neutralise which leaves a pH of 7
How acidic or basic the water is. You want it in the middle of these two. "PH" refers to the acid/base continuum. Low numbers mean higher acid concentrations, High numbers mean higher alkaline (base) numbers.
No, the math term ratio doesn't mean multiply.
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 0, that means that the concentration of H+ is equal to 1 molar, because -log(1) = 0. If you have a 1 M solution of any strong acid, the pH will be equal to zero.
In the term "pH," the "H" stands for hydrogen. pH is a measure of the hydrogen ion concentration in a solution, indicating its acidity or alkalinity.
pH is a scientific term, standing for potential hydrogen.
pH is a term used for liquids.
The term pH was created by Sorensen in 1909.
pH is term used in chemistry.
A pH over 7 is basic.A pH=7 is neutral.A pH under 7 is acid.
A pH over 7 is basic.
power of Hydrogen
In 1909 , Sorenson,a Danish biochemist,introduced the term PH.
The pH of the blood is regulated by short term changes mediated by altering the rate of respiration and on the longer term by filtering of the blood in the kidneys.
Possible 'power of hydrogen' as pH refers to the activity of hydrogen ions in a solution.
