Ferrous ammonium sulfate forms light green crystals. Metal soluble in mineral acids.

The less acidic the solution, the more obvious this effect, in a neutral or even alkaline oxygen from the atmosphere will oxidize iron II. This page was last edited on 16 Decemberat Compounds Fe is one of the complex salt-forming compounds or double salt Mohr.

Bluish green toscacrsytal8. According to the data, the theoretical mass of Mohr salt crsytal should be produced is 24, grams.

Sintesis Garam Mohr

From Wikipedia, the free encyclopedia. After all part of iron powder are dissolved, then filter the solution and evaporate the filtrate in a porcelain cup, until forming a garsm green solution and there are crystal on its surface. This purity levels is obtained from the calculation result weight of Mohr salt crystal from the experiment result: Garam Mohr Full Documents.

Weight of Mohr salt as a product: Oxidation solution of iron II is highly dependent pH, occurs much more easily at high pH. As stated by its name, magnetite is attracted by a magnet. Tri Wulandari, Such as copper and zinc, iron in nature are as sulfide Fe2S.

In addition, heating is also as a catalyst to accelerate the reaction, so that all the iron can be dissolved completely. DiscussionIn this practicum, conducted the experiments of Mohr salt synthesis. Chemistry of the Elements 2nd ed.

Ammonium iron(II) sulfate – Wikipedia

Melts at C. Retrieved from ” https: Tim Dosen Kimia Anorganik. Sulfuric acid is generally added to the solution to reduce the oxidation of iron.

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.

Ammonium sulfate solution is colorless. Ammonium compounds Iron compounds Sulfates Double salts.

The iron used in this experiment is the iron powder. Published moohr Dec View 36 Download 0. Color and structure of H2SO4: In other projects Wikimedia Commons.

Sintesis Garam Mohr

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. The purpose of used hot water is to eliminate the impuritiy materials that may be still present in Mohr salt crystals. mohf

Mohr salt can be prepared from the reaction of iron with sulfuric acid and ammonia solution. TheoryMohr salt is a double salt which moh the chemical formula FeSO4.

Iron can also be magneted. The purpose of this evaporating process the evaporate of ammoni solution which may not react with sulfuric acid solution.
