Gravimetric analysis

Gravimetric analysis

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte based on its mass. The principle behind this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative quantities of the other

Estimation of Iron (II) in an iron tablet by Calculations

Estimation of Iron (II) in an iron tablet by Calculations

To estimate the iron(II) content of an iron tablet, a small number of tablets are first dissolved in dilute sulfuric acid. This solution is then titrated against previously standardised potassium manganate(VII) solution. The reaction is represented by the equation MnO 4 + 8H + + 5Fe+2 Mn +2 + 5Fe +3 + 4H 2O METHOD Preparation of tablets
