Abstract

Filtration is a separation method for separating materials mechanically, with the aim of separating solids from liquids or gases. Has conducted lab using a sand filter to reduce the Fe content in the water with permangnometry analysis. Permanganometry titration should be done in the dark. Titration is carried out under acidic conditions. This reaction is focused on oxidation and reduction reactions that occur between KMnO4 to a certain standard solution. Results endpoint during the process of standardizing potassium permanganate indicated by the color of the solution changes to red rose. In this experiment conducted standardized KMnO4 by using a mixture of oxalic acid and determination of H2SO4 and FeSO4. Based on the calculations get the molarity of KMnO4 is 0.27 M, 0.04 M FeSO4 molarity and mass FeSO4 was 0.091 grams. Results endpoint during the process of determining the levels of iron (II) sulfate is indicated by the color of the solution changes to red, the color is obtained in the experiment when it was titrated with potassium permanganate volume of 2.4 ml so diperolehlah concentration of iron (II) sulfate ie 0.04 M and Fe concentration in a solution of iron (II) sulfate of 2.63% Keywords: Sand Filter, Water Household, Permanganometry
