ncert.nic.inThe titrations involving redox reaction are called r edox titrations. Y ou know that in acid-base titrations, indicators which are sensitive to pH change are employed to note the end point. Similarly, in redox titrations there is a change in oxidation potential of the system. The indicators used in redox reactions are sensitive to change in ...
Lecture 10 - Redox Titrations
www.calstatela.eduRedox indicators a. specific indicators – react with one of the participants in the titration to produce a color, e.g. thiocyanate b. Oxidation-reduction indicators- respond to the potential of the system rather than to the appearance or disappearance of some species during the course of the titration, e.g. methylene blue

ANALYSIS OF BLEACH BY THIOSULFATE TITRATION
seniorchem.comThe determination of free chlorine in bleach is possible by a redox titration. The most common and successful method for use in high schools involves taking the sample of bleach converting the hypochlorite ion (ClO-) to iodine (I 2) by the addition of KI and then titrating the iodine with

REDOX TITRATION - Weebly
chembloginc.weebly.comredox titrations: I2 + I-→ I 3-. The actual reaction that occurs in the redox titration is then between the tri-iodide ion and the thiosulphate ion. In this experiment, the thiosulphate is titrated against a known volume of a standard iodate in the presence of excess iodide. The endpoint is signaled by the disappearance of a blue
