Sintesis Garam Mohr

Metal soluble in mineral acids. Sulfuric acid solution is a solvent containing ionizable protons and strong acid or weak acid.

In ideal conditions, the result can be a single crystal, which all atoms in solids “attached” to the grid mkhr the same crystal structure, but in general, most of the crystals are formed simultaneously resulting polycrystalline solids.

Mohr salt or ammonium ferrous sulfate FeSO4. Sintesis Garam Mohr Download Report. Mhr and structure crystal of Mohr salt: Chemistry of the Elements 2nd ed. Garam Mohr Full Documents. Mohr’s salt is prepared by dissolving an equimolar mixture of hydrated ferrous sulfate and ammonium sulfate in water containing a little sulfuric acidand then subjecting the resulting solution to crystallization.

This purity levels is obtained from the calculation result weight of Mohr salt crystal from the experiment result: The purpose of filtering and evaporation of this is to avoid the formation of crystals at low temperatures and to reduce the water molecules mohe the solution. Crystal structure which is formed of a liquid, depends on the its fluid chemistry, when the solidification conditions and ambient pressure. So that this produced pure Mohr salt crystals that has bluish green color.


Fuady Hanief Laporan Prak. The ammonium ions make solutions of Mohr’s salt slightly acidic, which slows this oxidation process. Anonymous, Crystal or crystalline solid that is an atom, molecule, or ion constituent packed regular and repetitive pattern extends in three dimensions.

ObjectiveStudy the Mohr salt from the reaction between the iron with sulfuric acid and ammonia solutionB. For double salt with M is NH4, which made the number of moles of iron II sulfate and ammonium sulfate same, then the result is known as Mohr salt.

These minerals have the potential to be developed as an industrial material.

For example, most metals which we see everyday are polycrystalline. Thus obtained Mohr salt crystals with monoclinicic shape and has bluish-green color due to contained Fe with NH4 2SO4 which form complex compounds.

Ammonium iron(II) sulfate

Mohr’s salt is gara, after the German chemist Karl Friedrich Mohrwho made many important advances in the methodology of titration in the 19th century. So that this reaction produced light green solution. It is used in the Fricke’s dosemeter to measure high doses of gamma rays. Then a solution of iron II should be slightly acidic when you want to keep for a long time. By using this site, you agree to the Terms of Use and Privacy Policy.

In this experiment, all of the solution that used is concentratd solution, so that this experiment is johr in a fume hood because of the concentrated solution will cause a pungent odor and dangerous for practitioner. They are more stable than the salt, iron II. TheoryMohr salt is a double salt which has the chemical formula FeSO4.


DiscussionIn this practicum, conducted the experiments of Mohr salt synthesis.

The first step that we do in this experiment is make solution A, solution A is made by neutralizing the sulfuric acid solution with ammonia solution, so that this reaction produced the solution of ammonium sulfate. Other names Ferrous ammonium sulfate Ammonium iron sulfate Mohr’s salt.

Laporan Praktikum Penentuan Taram dan In the damp air quickly oxidized give iron III oxide hydrate rust are not able to protect, monr this substance is destroyed and let the new metal surface open.

Ammonium iron(II) sulfate – Wikipedia

Retrieved 13 June Purity levels of Mohr salt: In addition, heating is also as a catalyst to accelerate the reaction, so that all the iron can be dissolved completely.

Ions and complexes combined colored old tongs are also common. Fe compounds in the form moht Mohr salt or K4Fe CN 6 potential as a reducing agent in the reaction of iodate reduction in salt.
