ANALYSIS OF ASH AND MINERALS UMass Amherst

Colorimetric methods. These methods rely on a change in color of a reagent when it reacts with a specific mineral in solution which can be quantified by measuring the absorbance of the solution at a specific wavelength using a spectrophotometer. Colorimetric methods are used to determine the concentration of a wide variety of different minerals.

CHEMICAL PRECIPITATION WATER SOFTENING

Chemistry of Hardness Removal Process During precipitation softening, calcium is removed form water in the form of CaCO 3 precipitate and magnesium is removed as Mg(OH) 2 precipitate (Frederick W.

What is a Titration Purdue University

A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete. Knowing the volume of titrant added allows the determination of the concentration of the unknown.
