Explain step by step.What are the 3 ways to determine the completion of a coulometric titration
- What is the acid/base ratio is important in the titrimetric process?Is the standardization of titrant always the first step in all titrimetric analysis? Why or why not?Coulometry consumes larger amount of analyte than voltammetry The answer is either true or false Electrodes of the second kind can respond to the activities of anions that form sparingly soluble precipitates The equivalence point is at the first quarter of 3 the steep part of the titration curve when the reaction stoichiometry is 1:1. In order to be useful in endpoint detection, a redox indicator's range of color change should be at least double the potential expected at the end of the titration Membrane indicator electrodes are 5 sometimes called p-ion electrodes because they measure the pH only The IR drop refers to the deviation of the electrode potential from the value predicted by the Nernst equation on the passage of 6 current
