Self indicator in titration
WebAn indicator is a substance that changes colour in the presence of the ions that are taking part in the reaction. The endpoint of the titration is when the indicator changes colour. … WebJul 7, 2024 · Potassium permanganate may act as a self-indicator as it has a distinct purple color and becomes colorless on reduction. What is the indicator in Iodimetry? The indicator that is usually chosen for titrations involving iodine (triiodide) is starch. Starch forms a dark blue complex with iodine.

WebRedox Titration is a laboratory method for determining the concentration of an analyte. It is based on a redox reaction between the analyte and the titrant, and it may occasionally include a potentiometer or a redox indicator as part of the process. When we say that this titration is based on a redox reaction between the analyte and the titrant ... WebA titration curve can be used to determine: 1) The equivalence point of an acid-base reaction (the point at which the amounts of acid and of base are just sufficient to cause complete neutralization). 2) The pH of the solution at equivalence point is dependent on the strength of …
