25.00 ml of a 0.2000 mol/l potassium iodide solution in an acid
buffer medium (pH = 1.00) were titrated with a 0.06000 mol/l
potassium dichromate solution. Calculate the value of the
equivalent volume.
Data: Eo (Cr2O72- /
Cr3+) = 1.33 V; Eo
(I3- / I-) = 0.54 V
Homework Answers
First we have to calculate the
n factor of respective equations then we know for titration
purposes the normality of titrant and titrand is same so we have to
equalize both normalities and then we have the volume of potassium
dichromate used in reaction.
