What is the indicator used in the Alkalimetric titration?
This point is called the equivalence point and is generally determined by observing a color change in an added indicator such as phenolphthalein. From the volume and concentration of added base and the volume of acid solution, the unknown concentration of the solution before titration can be determined.
Can be Analysed by direct titration method?
Direct titration is the most basic titration which is commonly used. In this type, a titrant of known concentration and volume is added to a substance in order to analyze it. For determining the concentration of an analyte, one can use Indirect Titration also….Follow Pharmaguideline.

What is Acidimetric and Alkalimetric?
Acidimetry is the specialized analytic use of acid-base titration to determine the concentration of a basic (synonymous to alkaline) substances using standard acid. Alkalimetry, is the same concept of specialized analytic acid-base titration, but for an acidic substance using standard base.
How do you know if its Acidmeetry or alkalimetry?
The key difference between acidimetry and alkalimetry is that acidimetry is the measurement of the strength of acids, whereas alkalimetry is the measurement of the strength of alkaline compounds.
What is the indicator that changes color called?
end point titration
The point at which indicator undergoes colour change is called end point titration.
What is Alkalimetric titration?
Definition: The process of determining the quantity of a sample (a base) by adding measured increments of a titrant (an acid) until the endpoint, at which essentially all of the sample has reacted, is reached.
Which of the following can be analyzed by direct complexometric titration?
In this titration standard EDTA solution is added to given sample containing metals using burette till the end point is achieved. Copper, barium, zinc, mercury, aluminum, lead, bismuth, chromium etc. are metals which can be determined by using direct complexometric titration.
What is Acidimetric analysis?
“The term acidimetry refers to that part of volumetric analysis whereby an acid solution at known concentration, along with a specific indicator, is used to titrate a base solution and thus work out its concentration“.
What is Alkalimetric method?
What are the four types of indicators?
According to this typology, there are four types of indicators: input, output, outcome and impact.
What causes color change in titration?
The base strips H+ ions from the acid, and near the end of the titration, it starts pulling H+ ions from the phenolphthalein. Phenolphthalein is a unique molecule. When the H+ is stripped off, it changes color from clear to pink.
What is alkalimetric titration?
Referring to the name, alkalimetric titration is a method of measuring the base concentration of a solution using an acid standard solution. This type of titration is the type most frequently used. In alkalimetric titration, the base is used as the titrant which is then dropped into the acidic titrate solution, so that the solution becomes neutral.
What are the methods of residual titration?
(b) Residual Titration Methods : It is carried out by the addition of an excess of the standard alkali solution and subsequently determining the amount in excess by residual titration with standard acid solution. (i) the normality of the solution obtained by dissolving the acidic substance must be approximately the same as that of the titrant,
What is the difference between acidimetry and Alkalimetry?
Acidimetry involves the determination of acidic substances by titration with a standard base solution, and alkalimetry is the measurement of basic substances by titration with a standard acid. Neutrali- zation reactions represent one aspect of volumetric analysis.
What is titrimetric analysis in chemistry?
Titrimetric analysis involves determination of the volume of a solution of accurately known concentration, which is required to react quantitatively with the measured volume of the solution of a substance, concentration of which is to be determined. The solution of accurately known concentration is called standard solution.
