I am attempting to complete a question in which I need to use an ICE table to calculate the pH of a $\pu{2.61 mol L-1}$ $\ce{NH4HSO4}$ (ammonium hydrogen sulfate) solution. Persistence and degradability Ammonium Sulfate (7783 -20 -2) Persistence and degradability Not established. Ammonium Sulfate contains 21% nitrogen which makes a good fertilizer for any growing plants including evergreens. 12.4. Ph Eur - Find MSDS or SDS, a COA, data sheets and more information. Mobility in soil Ammonium sulphate fertilizer is a widely used, inorganic soil supplement that has particular benefits when applied to alkaline soils. Bioaccumulative potential Ammonium Sulfate (7783 -20 -2) Log Pow -5.1 Bioaccumulative potential Not established. In greenhouse studies, the effect of carrier water pH (4, 6.5, and 9), foliar fertilizer (zinc [Zn], manganese [Mn], or without fertilizer), and ammonium sulfate (AMS) at 0% or 2.5% vol/vol was evaluated on 2,4-D and premixed 2,4-D plus glyphosate efficacy for giant ragweed, horseweed, and Palmer amaranth control. 12.3. Applying certain fertilizers, such as ammonium-containing nitrogen fertilizers like ammonium sulfate, urea or ammonium sulfate, can help maintain acid soil conditions, but these fertilizers will probably not be effective in significantly reducing soil pH. However, due to 24% Sulfur content, Ammonium Sulfate will lower the pH level of the soil as well so you need to make sure your soil pH level doesn't drop too much. Ammonium sulfate CAS 7783-20-2 for analysis EMSUREĀ® ACS,ISO,Reag. When $\ce{NH4HSO4}$ dissociates I know that it splits into $\ce{NH4+}$ and $\ce{HSO4-}$ ions. The ammonium in these products reacts in the soil to help maintain the lowered pH. Ammonium sulfate has an acidifying effect on soil due to the nitrification process, not from the presence of sulfate, which has a negligible effect on pH. High Grade Analar ammonium sulfate should be used, as the lower-grade material is frequently contaminated with heavy metal ions which can affect subsequent assays. The active ingredients in it are nitrogen and sulfur.Correct use of this fertilizer maintains healthy nitrogen levels in the soil and, in the case of alkaline soils, helps to maintain a good pH balance. Ammonium sulfate, analytical standard, for Nitrogen Determination According to Kjeldahl Method, traceable to NIST SRM 194, 204501 Ammonium sulfate, 99.999% trace metals basis, Ammonium Sulfate (7783 -20 -2) LC50 fish 1 36.7 mg/l EC50 Daphnia 1 433 mg/l 12.2.
