Volumetry

From a measurement pipe, drops of a reagent are dripped into the solution of a sample to be analyzed until an indicator shows that the sample has been consumed. The ratio of the contents and volumes of both solutions yields the content of the material in the sample.

Initially, a special measurement instrument is developed for each method in the field of volumetry. In 1855 Friedrich Mohr publishes a summary of the methods known in his day and constructs a universal titration instrument. Natural rubber hoses and the bead valve replace the fragile glass spouts. The liquid is calibrated in fractions of a liter at a standardized temperature. Now the contents of a soluble material in a sample can be determined quickly and precisely.
