How do you measure permanent hardness by EDIT titration?
To measure permanent hardness by EDTA titration, first add a buffer solution to the water sample to maintain a stable pH. Then, titrate with standardized EDTA solution until the color changes indicating the endpoint. The volume of EDTA required to reach the endpoint can be used to calculate the concentration of the ions causing permanent hardness in the water.
What are different types of EDTA titration?
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
How you can do EDTA titration reaction?
To perform an EDTA titration, first prepare a solution containing the analyte (the substance being measured) and a suitable indicator, such as Eriochrome Black T. Add a standardized solution of EDTA to the analyte solution until the endpoint is reached, indicated by a color change in the indicator. The volume of EDTA solution added can be used to calculate the concentration of the analyte based on the stoichiometry of the reaction.
How do you prepare methyl red for titration?
To prepare methyl red for titration, first make a stock solution by dissolving the dye in a suitable solvent such as water or alcohol. Then, carefully add the desired amount of the stock solution to your titration flask based on the concentration needed for your specific experiment. Finally, ensure proper mixing before using the solution for titration.
Why Gycerol is used for the titration of NaOH with Borax?
cuz' borax contain boric acid (H3BO3) which is very weak acid , thus it gives non accurate titration, so we add neutral glycerol to increase the acidity by the way we add glycerol after titration of NaOH not before

Why we add buffer to standardization of ED-TA solution?
Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.
How many grams of EDTA do you add to make a 3.7 percent EDTA solution?
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.

Why is indicator added to a pipette solution before titration?
I'm not sure what you really mean. There wouldn't be any point adding it afterwards! It's there to reveal the end point of your titration. You could add it when you thought you were near the end point, but it's easier to put it in before you start.
Why you add starch at the end of titration?
Starch is added at the end of titration as an indicator to signal the endpoint of the reaction. It forms a complex with the iodine produced during the titration, resulting in a color change from clear to blue-black, indicating that the titration is complete.
