Mohr’s Method of Precipitation Titration

MOHR’S METHOD OF DETERMINATION OF CHLORIDES BY TITRATION WITH SILVER NITRATE is one of the oldest titration methods still in use – it was researched and published by Karl Friedrich Mohr in 1856.The idea behind this titration is very simple – chlorides are titrated with the silver nitrate solution in the presence of chromate anions. … Read more

Accuracy and Precision

Accuracy In analytical chemistry, the term ‘accuracy’ is used in relation to a chemical measurement. The International Vocabulary of Basic and General Terms in Metrology (VIM) defines accuracy of measurement as… “closeness of the agreement between the result of a measurement and a true value.” The VIM reminds us that accuracy is a “qualitative concept” … Read more

Methods of Minimizing Errors

Minimizing Systematic Error Systematic error can be difficult to identify and correct. Given a particular experimental procedure and setup, it doesn’t matter how many times you repeat and average your measurements; the error remains unchanged. No statistical analysis of the data set will eliminate a systematic error, or even alert you to its presence. Systematic … Read more
