There are many popular indicators in chemistry for measuring the pH (or pOH) level of a substance, and they are referred to collectively as pH tests.
A litmus test is among the more popular of the tests and is usually used in the form of a strip of paper which functions as a dipstick. The paper (purple when neutral, though sometimes pale pink or pale blue to start with in commercial products) will turn red for a pH below 4.5 (acidic) and blue above 8.3 (basic). However, this leaves the alkaline range ambiguous, so it is not ideal for testing for the alkalinity of a substance.
Phenolphthalein is most commonly used in acid/base titrations to find the point of alkalinity and is very accurate. It is in liquid form and can be added to the chemical to be tested. On its own or in an acid phenolphthalein is completely clear, but in a basic solution a single drop can turn even a beaker-full a bright magenta. A very pale "rosy pink" will occur at equilibrium and is generally used in titrations to indicate alkalinity.

What is the strength of an acidic solution called?
i believe its called alkalinity
What is active alkalinity?
Alkalinity is divided into two main parts, active and inactive. Active alkalinity titrates to a pH of 8.4 and is responsible for the cleaning action of alkaline products.
What does alkalinty mean?
You mean alkalinity? Alkalinity measures the ability of a solution to neutralize acids to the equivalence point of carbonate or bicarbonate. The alkalinity is equal to the stoichiometric sum of the bases in solution.
What is PH up?
High alkalinity
What is the acidity or alkalinity of a substance called?
seamen
How acidity and alkalinity measured?
Using the pH scale.
Why alkalinity is measured as CaCO3 Eq?
as for convenience we used CaCo3
What does the mean of m alkalinity and p alkalinity water?
1. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of "ppm as calcium carbonate". ( M-Alkalinity measurement is based on a sulphuric acid titration using a Methyl orange indicator that goes from yellow at a pH of 4.5 to orange at pH of 4.4 at the endpoint.) 2. P-Alkalinity measures the amount of carbonate and hydroxyl alkalinity present in terms of "ppm as calcium carbonate". P-alkalinity is measured down to a pH of 8.3. The M-alkalinity is measured down to a pH of 4.3.
What does the mean of m alkalinity and p alkalinity in boiler water?

The M-alkalinity is measured down to a pH of 4.3.
How alkalinty is measured?
If im correct about alkalinity scientificaly. Its measured in pH scale 1 2 3 4 5 6 7 8 9 10 11 12 13 14 ______________________________________ Acid Neutral Alkaline
Alkalinity of pool?
Alkalinity is common baking soda. Hatawa
Difference between phenolphthalein alkalinity and and total alkalinity?
phenolphthalein alkalinity is due to hydroxide n carbonate salts in water...nd total alkalinity is mainly due to bicarbonate salts in water..
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 the strength of an acidic solution called?
i believe its called alkalinity
What do you measure hydrochloric acid in?
Hydrochloric acid can be measured in units of concentration, such as molarity (moles per liter) or normality (equivalent grams per liter). It can also be measured using pH, which indicates the acidity or alkalinity of a solution, or by titration with a suitable base to determine its concentration.
What is active alkalinity?
Alkalinity is divided into two main parts, active and inactive. Active alkalinity titrates to a pH of 8.4 and is responsible for the cleaning action of alkaline products.
What is alkalinity value?
The word alkalinity is defined by the ability that any substance has at neutralizing when it is mixed with an acid.
