Lecturer of Inorganic Chemistry Team, C. Then a solution of iron II should be slightly acidic when you want to keep for a long time. Laporan Sintesis Garam Rangkap Documents. There is rarely a purely commercial iron, iron usually contain small amounts of carbides, silicides, phosphides, and sulfides of iron, and a little graphite.

Sintesis Garam Mohr Download Report. In analytical chemistrythis salt is the preferred source of ferrous ions as the solid has a long shelf life, being resistant to oxidation. Pure iron is quite reactive. They are more stable than the salt, iron II. This page was last edited on 16 Decemberat Fuady Hanief Laporan Prak.

Petunjuk Praktikum Kimia Anorganik. Retrieved 13 June Ammonium iron III sulfate. In the damp air quickly oxidized give iron III oxide hydrate rust are not able to protect, because garm substance is destroyed and let the new metal surface open.

In this experiment obtained 5, grams of Mohr salt crystal. The purpose of filtering and evaporation of this is to avoid the formation of crystals at low temperatures and to reduce the water molecules in the solution.


Reaction occured in the experimen: Tri Wulandari, Such as copper and zinc, iron in nature are as sulfide Fe2S. This purity levels is obtained from the calculation result weight of Mohr salt crystal from the experiment result: Bijaksana, The properties of very smooth iron is pyrophoric. If mmohr solution containing chloride, the color becomes stronger.

Evaporating ammonium sulfate solution until saturatedHeating ang let the iron powder dissolve by stirringH. The calculation of the theoretical weigh of Mohr salt: Ions and complexes combined colored old tongs are also common.

Sulfuric acid is generally added to the solution to reduce the oxidation of iron. Dilute or concentrated hydrochloric acid and dilute sulfuric acid gatam the iron, in which the resulting salts of iron II and hydrogen gas.

Crystal structure which is formed of a liquid, depends on the its fluid chemistry, mobr the solidification conditions and ambient pressure. After cooled, the mixture solution is filtered to separate the solution with Mohr salt crystals.

But it is not used as a mineral ore as remnants of trace sulfur difficult to remove. Ammonium ions make Mohr salt solution slightly acidic, which slows down the oxidation process.

Ammonium sulfate mour is colorless. Purity levels of Mohr salt: Thus obtained Mohr salt crystals with monoclinicic shape and has bluish-green color due to contained Fe with NH4 2SO4 which form complex compounds.


Observation Data and Analysis Data1. In this experiment, all of the solution that used is concentratd morh, so that this experiment is done in a fume hood because of the concentrated solution will cause a pungent odor and dangerous for practitioner.

Ammonium iron(II) sulfate – Wikipedia

Diakses pada tanggal 15 April pukul Anonymous, Crystal or crystalline solid that is an atom, molecule, or ion constituent packed regular and repetitive pattern extends in three dimensions. Retrieved from ” https: In ideal conditions, the result can be a single crystal, which all atoms in solids “attached” to the grid or the same crystal structure, but in general, most of the crystals are formed johr resulting polycrystalline solids.

At the time of cooling results in both salt mixture above will be obtained crystal bluish green with monoclinicic form. DiscussionIn this practicum, conducted the experiments of Mohr salt synthesis. These minerals have gadam potential to be developed as an industrial material.
