Dec 19, 2024 · Precipitation titrations are fundamental techniques in analytical chemistry, offering simplicity and generating a large data set in a short time. This laboratory experiment introduced …

The Mohr method was first published in 1855 by Karl Friedrich Mohr. Because CrO 4 2 imparts a yellow color to the solution, which might obscure the end point, only a small amount of K 2 CrO 4 is added. …

Apr 16, 2024 · As more SCN is added, the red color returns which introduce a huge error in analysis. To avoid this error, a solution of a few milliliters of an organic liquid that will not mix with water must be …

The choice of titration method is critical when analyzing mixtures of chloride and iodide. The following sections compare the performance of common argentometric methods in the presence of this …

2 - Titration of iodide and thiocyanate is not successful because AgI and AgSCN absorb chromate ions so strongly that a false end point is obtained . 3 - The Mohr’s method is not suitable to the …
