The pH scale is mostly in the range 0-14. A pH value of 7.0 means neutral. The lower the value, the more acidic the substance. The higher the value, the more alkaline. Note that, pH can be 15, just like it can be -1.

What is meant by the term alkalinity?
The word 'alkalinity' means pH values above 7
On what scale is acidity measured?
The pH scale - pH stands for percent-Hydrogen; indicating that the scale tests the concentration of free hydrogen bonds in a known solution. The higher the concentration of hydrogen bonds, the more acidic a solution; the lower the concentration of hydrogen bonds, the more alkaline or basic a solution. The scale ranges from 0-14, with 0 being the most acidic solution and 14 being the most alkaline (basic). A pH reading of 7 is a neutral substance - it is neither acidic nor basic. The pH is the measure of the acidity or alkalinity of a solution
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
If you have a lower pH will you have higher proton concentration?
Yes. The pH scale is an inverse log scale of the [H].
Where does pH come from?
pH is the measure of acidity/alkalinity, 7 being neutral pH, 1 being typically regarded as the most acidic and 14 being typically regarded as the most alkaline. The pH is usually measure using coloured titration reaction, litmus paper or a digital pH meter. And now for the science. The scale for pH i clearly a strange number for a start, up to 14. The reason for this is that pH is a log scale, in truth it is a negative log scale. It was designed the way it is because the concentration of H ions was so small that is was impractical to write all the 00000s out every time. To find the pH from a concentration of hydorgen ions is fairly simple, -log[H]. No really that's it. To find it from the concentration of OH ions is a little trickier and im no chemist so i don't remember.
How acidity and alkalinity measured?
Using the pH scale.
What is the pH indicator scale?
it indicate the acid and base of the scale
What is the pH scale actually representing?
pH is a measure of acidity/alkalinity of a solution.The classic pH scale is between 0 and 14.
What impact has the pH Scale had on science?
a pH Scale is a range from 0 to 14 0 to 6.9 is acidity 7 is neutral 7.1 to 14 is alkalinity the pH scale is logarithmic
What do mean pH scale?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
What is pH scate?
numeric scale used to specify the acidity or alkalinity of an aqueous solution
What do scale mean?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
What is soil pH?
Soil pH is the pH value of the particular soil mixture.AnswerIt is a measure of the degree of acidity or alkalinity in the soil. 7 is neutral on the scale.
What is the alkalinity of spirulina?
Spirulina is an alkaline food which means it counter the acidic foods and help raise the pH level towards the alkaline side of the scale. Alkalinity of spirulina is in the range of 8 to 11 pH.
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 scale is used to indicate whether something is acid or alkaline?
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
What name is given to the scale that measures acidity and alkalinity?
It is called the pH scale, which is usually considered to mean "power of hydrogen" (acids having a pH of less than7, bases having a pH more than 7).
