In a titration, a solution of known concentration (the titrant) is slowly added to a solution of unknown concentration until the reaction is complete. This reaction can be monitored using an indicator that changes color when the reaction is complete. The volume of titrant required to complete the reaction can then be used to determine the concentration of the unknown solution.

What is the scout titration?
The scout titration is a preliminary titration carried out to estimate the approximate endpoint in a titration experiment before performing the actual titration. It helps in determining the approximate volume of titrant required for the main titration to avoid overshooting the endpoint.
Why the titration have to be carried out immediately after the addition of sulphuric acid?
Titration should be carried out immediately after the addition of sulfuric acid to prevent any chemical reactions or changes in the sample that could affect the accuracy of the titration results. Waiting could lead to altered concentration levels or other undesired reactions that could affect the titration process.
What is the trial titration?
A trial titration is carried out before the actual titrations and is not recorded. It is carried out by adding increments of several milliliters from the reactant in burette. It helps to give a rough estimation to the end point.
Why do we carryout blank titration in argentometric titration?
Blank titration is carried out in argentometric titration to account for any impurities or contaminants present in the reagents used. By measuring the volume of titrant required to reach the endpoint in the blank titration, this value can be subtracted from the volume used in the actual titration to determine the accurate amount of titrant required to react with the analyte.
Why the solution is boiled before titration?
Boiling the solution before titration helps to remove any dissolved gases that may interfere with the titration process. Additionally, heating the solution can help to dissolve the solute more effectively and improve the accuracy of the titration results.
What is Back titration?
A back titration is a form of titraiton in which an excess of standard reagent is added and then the reverse of the titration is carried out.

What is a back titration?
A back titration is a technique used in analytical chemistry to determine the concentration of an analyte by reacting it with an excess of a known reagent, then back-titrating the remaining excess reagent. This method is useful when the analyte reacts slowly or incompletely with the titrant in a direct titration.
Why must the titration be carried quickly and diffuse?
To minimize the chance of side reactions, errors, or contamination from the surroundings. A slow titration could result in inaccurate results due to reactions with air or impurities. Rapid titration helps to ensure more precise and reliable measurements.
Why thiosulphate titration is called as redox titration?
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
What is the importance of standardizing a solution before titration?
Standardizing a solution before titration is important because it ensures the accuracy and reliability of the results. By knowing the exact concentration of the solution being used, the titration process can be carried out with precision and consistency. This helps to avoid errors and discrepancies in the final measurements, leading to more reliable and meaningful data.
What difference between titration and back titration?
In fact, a back titration is carried out as in a very similar method to an ordinary titration. the only difference is in the context. Consider an unknown acid solution. Then a known amount of excess alkali was added to the solution and made them react. Then the process of finding the amount left from the alkali is known as the back titration.
Why is the titration not carried in acid medium in edta method?
Titration is not carried out in an acid medium in EDTA method because at low pH levels, the formation of metal-EDTA complexes is hindered, leading to inaccurate results. The EDTA molecule itself is stable at a slightly alkaline pH, which enhances its chelating ability and ensures more accurate complex formation with metal ions.
