In this type, a titrant of known concentration and volume is added to a substance in order to analyze it. It includes Direct Titration and Indirect Titration. A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent.The remaining excess reagent is then titrated with another, second reagent. The second titration's result shows how much of the excess reagent was used in the first titration, thus allowing the original analyte's concentration to be calculated. The basis of these two types of titrations is oxidation-reduction, and we can use it to determine redox species quantitatively. solution. Behaviour of Iodine. The titration with standard iodine solution can only happen with a good indicator. indirect and direct. Route of Titration. Near infrared spectroscopy (NIR), out of all indirect methods, is extensively investigated for the determination of moisture content [4, 5]. The excess silver is then back titrated using a standardized solution of potassium or ammonium thiocyanate with ferric ion as an indicator. This is used when the end point of the primary titration is difficult or impossible to determine. The indirect FA technique was successfully used for the titration of group antibody in human serum. This titration mostly is applied at indirect titration: the substance to investigate is replaces by Iodine or Tio, dependent on the question: was the unknown substance an oxydator or a reductor? Direct titrations have disadvantage of the lack of distinct inflection points in the titration curves and the overlap of pKa values of acidic groups, and because of that indirect titration is still in use, even though it itself shows some limitations, as well [9,19-21]. Direct titrations have disadvantage of the lack of distinct inflection points in the titration curves and the overlap of pKa values of acidic groups, and because of that indirect titration is still in use, even though it itself shows some limitations, as well [9,19-21]. An Iodometric titration is an indirect method of analysis. Indirect Titration, doesn’t involve measuring the substance itself but knowing the quantity of a reagent to be added with a specific reaction and a titration is done to determine the unknown excess. (also vice-versa). of Redox Reactions. Carboxyl groups do not interfere, and a greater accuracy and reproducibility are obtained than in any of the indirect methods used. The acid that remained can be determined by titration with a base, could be: NaOH(aq). A new direct potentiometric titration method for the determination of oxirane oxygen has been developed. A substance can be weakly acidic and so it does not permit a precise analysis by direct titration. This method is applicable to a great variety of epoxy compounds and epoxy plasticizers. Indirect procedures involve addition of an excess of bromine, a period of time for reaction, and determination of the unconsumed bromine. Iodimetry is a direct titration method where the analyte under investigation is supposed to be a reducing agent. Potassium is precipitated as potassium sodium cobaltinitrite and dissolved in hot water containing little hydrochloric acid. However, it is more common to use Iodometric methods for analysis rather than Iodimetric methods. The volhard method is an indirect or back titration method in which an excess of a standard solution of silver nitrate is added to a chloride containing sample solution. Iodometry is an indirect titration method whereas iodimetry is a direct titration method. In this analyte (containing metal) is added in metal-EDTA complex. In this type of titration, the solution containing the unknown substance is kept in the bottom flask and the solution of known titrant is filled in the burette. solution is determined by titration with another std.
