Many different pH indicators exist, covering different ranges of acidity and alkalinity. Every pH indicator should come with its color guide to help determine the approximate pH level of whatever's being tested. The best way to determine the color's pH indication is a spectrometer.

What is the unit of basicity?
There is no specific unit for basicity. Generally we use pH scale to measure the basicity or acidity. it is between 1 to 14. towards 1 it is acidic and towards 14 it is basic.as per Wikipedia definition of pH is as followspH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution.[2]pH is mainly to measure acidity of compounds andpOH is for basic compounds.pOH is sometimes used as a measure of the concentration of hydroxide ions, OH−, or alkalinity.or pOH ≈ 14 − pH.
What indicators do you use to measure time?
A clock. Sun, moon , seasons.
What is the use of acid value?
The acid value is a measure of the acidity of many organic materials.
What is the difference between free acidity and total acidity?
Titratable acidity & Total acidity in wine: Total acidity: proton equivalence of the amount of organic acid anions present in a wine. It is the number of protons + dissociation. Titratable acidity: number of protons recovered during a titration with a strong base to a specified endpoint. It can also be expressed as a molar quantity. Many people use titratable acidity and total acidity as synonyms, but they are not. The titratable acidity is always less than the total acidity, because not all of the hydrogen ions expected from the acids are found during the determination of titratable acidity. However, titratable acidity is easier to measure.
What does a pH scale measure?
It indicates the concentration of H+ ions in an aqueous solution. It measures the acidity or alkalinity of a liquid. A pH of 7 (green with universal indicator) denotes Neutral. Anything below that is acidic, and anything above it is alkaline or basic. For everyday use, the pH scale goes from 1 (red) to 14 (purple). *The pH scale measures the concentration of H+ ions (or the acidity/alkalinity) in a solution. It is found by log-1 [H+], and ranges on a scale from 1 to 14 with 1 being the most acidic solution, 14 being the most basic solution, and 7 being neutral.
Why would you use an acidity regulator?
You would use an acidity regulator to control the acid level in your recipe. This ensures that you do not have too much or too little acidity.
Can you use indicator's for your car in GTA iv?
but other cars uses the indicators how? but why we cant use the indicators
What is the point at which a base permanently changes the color of an acid solution?
Acidity does not in itself have any color, and there is no specific pH at which a solution will necessarily change color (temporarily or permanently) however, there are some chemicals called indicators which can be added to a solution in order to create colors that will react to changes in pH. Since there are a number of different indicators that you can use, again there is no specific pH, it depends upon what you are using.
How do you test the acidity of soils?
use a ruler
Inventions that use indicators?
Pregnancy tests :)
Why do scientists use indicators?
to indicate something
How do you measure pH balance?
The pH tells the Acidity (or Hydrogen Ion Concentration) of the solution. The range of this measure is from 0 to 14, with Neutral being pH7. The lower the pH, the most Acidic end and, a pH above pH7 is Caustic.
