It contains 21% nitrogen and 24% sulfur asked by Anonymous on November 3, 2009; chem. The chemical equation shows how ammonia reacts with sulfuric acid to produce ammonium sulfate. express your answer using four significant figures. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. You can write the percent composition of nitrogen in ammonium sulfate by dividing the molar mass of the two nitrogen atoms by the molar mass of the compound, and multiplying the result by 100. Properties. Ammonium sulfate is especially useful as a precipitant because it is highly soluble, stabilizes protein structure, has a relatively low density, is readily available, and is relatively inexpensive. Global Ammonium hydrogen sulphate (CAS 7803-63-6) market size was ** billion USD in 2019, and will expand at a CAGR of **% from 2020 to 2025, according to the report. Ammonium sulfate, (NH 4) 2 SO 4, is an important ingredient in many artificial fertilisers supplying to plants the essential mineral elements of nitrogen and sulfur. Calculate the percentage of platinum in ammonium chloroplatinate (NH 4) 2 PtCl 6. These relative weights computed from the chemical equation are sometimes called equation weights. This is the percentage by mass of a component of a material with respect to the molar mass of that material. First, count the number of each element in the ammonium sulphate. The resulting acid mixture is then heated with excess of sodium hydroxide. All rights reserved. 2. Again, make sure your mass percents add up to 100%. Explanation: The chemical formula of ammonium sulfate is . Chemically speaking, it is the bicarbonate salt of the ammonium ion. Dilution with water will increase the evolution of Hydrogen sulfide vapors. (The formula for ammonium nitrate is NH 4 NO 3, Relative atomic masses: H = … Potassium nitrate, KNO3, and ammonium sulphate, (NH4)2SO4, are two nitrogenous fertilisers. Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils.
