The physical form of salt Mohr is greenish crystals. Then the solution is evaporated until the volume is reduced about a half of its volume before heating. Tri Wulandari, Such as copper and zinc, iron in nature are as sulfide Fe2S. The iron used in this experiment is the iron powder. It is used faram the Fricke’s dosemeter to measure high doses of gamma rays.

Ferrous ammonium sulfate Ammonium iron sulfate Mohr’s salt. Magnetic minerals in the upper third digunakansebagai also dyes and mixtures filler for the paint as well as the basic material for permanent industrimagnet. DiscussionIn this practicum, conducted the experiments of Mohr salt synthesis. By using this site, you agree to the Terms of Use and Privacy Policy. In other projects Wikimedia Commons.

In addition, heating is also as a catalyst to accelerate the reaction, so that all the iron can be dissolved completely. Mohr salt or ammonium ferrous sulfate FeSO4. Ammonium iron III sulfate. The purpose of filtering and evaporation of this is to avoid the gzram of crystals at low temperatures and to reduce the water molecules in the solution.


The calculation of the theoretical weigh of Mohr salt: Weight of Mohr salt as a product: Ammonium sulfate solution is colorless.

The ammonium ions make solutions of Mohr’s salt slightly acidic, which slows this oxidation process. Ammonium compounds Iron compounds Sulfates Double salts. Purity levels of Mohr salt: Petunjuk Praktikum Kimia Anorganik.

Ammonium iron(II) sulfate – Wikipedia

Crystal structure which is formed of a liquid, depends on the its fluid chemistry, when the solidification conditions and ambient pressure. Monr 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 Gaarm salt.

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. After all part of iron powder are dissolved, then filter the solution and evaporate the filtrate in a porcelain cup, until forming a light green solution and there are moh on its surface.

Evaporating ammonium sulfate solution until saturatedHeating ang let the iron powder dissolve by stirringH. Melts at C.

Sintesis Garam Mohr

Lecturer of Inorganic Chemistry Team, C. Laporan Sintesis Garam Rangkap Documents. Observation Data and Analysis Data1. Bijaksana, The properties of very smooth iron is pyrophoric.

Then a solution of iron II should be slightly acidic when you want to keep for a long time. Tim Dosen Kimia Anorganik.

Ammonium iron(II) sulfate

PT Kalman Media Pustaka. There is rarely a purely commercial iron, iron usually contain small amounts of carbides, silicides, phosphides, and sulfides of iron, and a little graphite.


In the damp air quickly oxidized give iron III oxide hydrate rust are not mphr to protect, because this substance is destroyed and let the new metal surface open.

In this experiment, all of the solution that used is concentratd solution, so that this experiment is done in a fume hood because of the concentrated solution will cause a pungent odor and dangerous for practitioner. The first step that we do in this experiment is faram 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.

These minerals have the potential to be developed as an industrial material. At the time of cooling results in both salt mixture above will be obtained crystal bluish green with monoclinicic form.

Laporan Pembuatan Garam Mohr Documents. After cooled, the mixture solution is filtered to separate the solution with Mohr salt crystals. Published on Dec View 36 Download 0.

Contaminants have played an important role in the strength of the iron structure. Anonymous, Crystal or crystalline solid that is an atom, molecule, or ion constituent packed regular and repetitive pattern extends in three dimensions.
