Can ammonium sulfate be contained in a general fertilizer or is it a separate product?
Q. A general fertilizer being one with Nitrogen , Phosphorus and Potassium. Could ammonium sulfate comprise a portion of the Nitrogen? Or is it a separate product?
Asked by Heather C - Fri Apr 30 12:19:58 2010 - - 2 Answers - 0 Comments
A. No it's sold separately like Sulfate of Potash and is primarily used to improve the acidic levels in soils.If you're in the UK, Bowers or Westland sell them in value pack cartons.

How do you calculate the concentration of ammonium and sulfate ions?
Q. A solution is prepared by dissolving 12.1 g ammonium sulfate in enough water to make 100.0 mL of stock solution. A 13.00 mL sample of this stock solution is added to 58.00 mL of water. Calculate the concentration of ammonium ions and sulfate ions in the final solution. Thank you!

A. moles ammonium sulfate = 12.1 g / 132.14 g/mol= 0.0916 M = 0.0916 / 0.100 L = 0.916 moles in 13.00 mL = 0.916 x 0.01300 L = 0.0119 new concentration = 0.0119 / ( 0.013 + 0.058) = 0.168 M [NH4+] = 2 x 0.168 = 0.336 M [SO42-] = 0.168 M

Asked by Dani [ ] - Mon Mar 8 21:26:24 2010 - - 2 Answers - 0 Comments
A. NH4 has a posotive charge of 1. there are 2 NH4's. This makes the total posotive charge +2. SO4 has a negative charge of -2. There is one SO4. this makes the total Negative charge -2. +2 -2 =0 this is good. a perfect octet has been achieved. however this is completely unrelated to the molar mass. To find the molar mass, add 2 Mole of nitrogen, 4 moles of hydrogen (NH4)v2 then add 1 mole Sulfur and 4 moles Oxygen (SO4) Add all those moles up and you get the molar mass of Ammonium Sulfate. (NH4)v2SO4

A. "In chemistry, fractional crystallization is a method of refining substances based on differences in solubility. If two or more substances are dissolved in a solvent, they will crystallize out of solution (precipitate) at different rates. Crystallization can be induced by changes in concentration, temperature or other means. A process by which a chemical compound is separated into components by crystallization. In fractional crystallization the compound is mixed with a solvent, heated, and then gradually cooled so that, as each of its constituent components crystallizes, it can be removed in its pure form from the solution" (NH4)2SO4: Solubility in water 70.6 g/100 mL (0 C) 74.4 g/100 mL (20 C) 103.8 g/100 mL (100 C)[ NaCl… [cont.]

Why can't ammonium sulfate be directly added to a phosphate buffer?
Q. Why can't ammonium sulfate ((NH4)2SO4) be directly added to a 15 mM pH 7.5 phosphate buffer made from KH2PO4 and titrated with KOH? Specifically, for a class experiment, the effect of 1M ammonium sulfate on 15 mM pH 7.5 phosphate buffer on its pH is supposed to be tested. I know the ion effects will drive the pH down, but in the instructions it mentions that the solution cannot be made simply by adding the correct amount of solid ammonium sulfate to a stock solution of phosphate buffer. No explanation is given, and I can't really come up with one.
