pH scale...... for acidity it is 0-6.9, neutral is 7.0, Basic is 7.1-14.0

What is the pk values of phosphoric acid?
acidity level
Why is the pH scale numbered from 0-14 instead of some other number range?
The pH scale is numbered from 0-14 because it corresponds to the concentration of hydrogen ions (H+) in a solution. A pH value of 7 is considered neutral, while values below 7 are acidic and values above 7 are alkaline. The range of 0-14 allows for a comprehensive representation of acidity and alkalinity levels in a solution.
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
the rf values would increase
What is a stronger pH value 1.5 or 4?
That depends on what you are referring to, a stronger base or acid. The pH scale logarimithically scales back the concentration of H3O+ in solution such that lower values conincide with greater degrees of acidity (specifically a magniture of 10 for each whole value). The stronger acid of the two values is most certainly 1.5, however the stronger base is 4
Where you could find the standard Rf values for fatty acids and poly unsaturated fatty acids?
Rf value of oleic acid with solvent system
A range of values that are used to express the activity or alkalinity of system?
I think you mean the 'acidity', not the activity, of a system; in which case the answer is pH. pH is a measure of the acidity or alkalinity (how basic something is) of a system. pH values range from 1 to 14, with 1 being the most acidic and 14 the most basic. It works on a log scale; i.e., a pH of 2 is ten times more basic than a pH of 1.
What are the pH numbers?
pH values are indications of acidity/alkalinity of a solution.
What is the range of values that are used to express the acidity or alkalinity of a system?
The pH scale. The pH scale goes from 0 to 14. Substances that have a pH of 7 are neutral, acids have a pH of less than 7, and bases have a pH of greater than 7.
What does the pH levels measure?
Tha acidity or alkalinity of a substance on a scale of 0 to 14. Values less than 7 are acidic. Values greater than 7 are alkaline. 7 is neutral.
What is acidity and alkalinity?
Acidity and alkalinity are terms used to describe the concentration of hydrogen ion (H+) in a solution. It is measured with the pH scale, a set of values usually given as 1 to 14 where 1 is very acidic, 7 in neutral, and 14 is very alkaline. The numbers are the negative log of the H+ ion's mole concentration. pH is measured with a pH meter or various indicator solutions which change colour at different pH levels.
What is meant by the term alkalinity?
The word 'alkalinity' means pH values above 7
Can pH value be related to acidity?
Yes to lower acidity you can add alkalines which increase Ph values
What is the pk values of phosphoric acid?
acidity level
What is does the pH do as nutrition?
Nothing. pH values indicate acidity levels.
Who is employed to express the values of interest groups?
lobbyists
Why do you express respiratory gas values in the body as partial pressures?
not sure
What is the system of values on mars?
Mars is not known to have any inhabitants, which are the ones that would have a "system of values".
