Ammonia is a weak base and forms a few ammonium and hydroxide ions in solution: NH 3 (g) + H 2 O (l) ⇌ NH 4+ (aq) + OH – (aq) The hexa-aqua-copper (II) ions react with hydroxide ions to form a precipitate. This involves deprotonation of …
In this case, the solution must have a molarity of 6 mol L−1, which is equivalent to saying that it must contain 6 moles of ammonium sulfate per liter of solution. Use this value as a conversion factor to find the number of moles that you'd get in 0.25 L of solution 0.25L solution ⋅ 6 molesa(NH4)2SO4 1L solution = 1.5 molesa(NH4)2SO4

2 N H 3 + H S O 4 → ( N H 4) 2 S O 4 The majority of sulphuric acid is used for the preparation of fertilizers for commercial uses. Therefore, sulphuric acid reacts with ammonium hydroxide solution or ammonia to prepare ammonium sulphate ( N H 4) 2 S O 4 . Sulfuric acid is also used in various productions of different paints and detergents.
Making ammonium sulfate . Ammonium sulfate is a complex fertiliser.This simple salt is a source of two nutrients nitrogen – and sulfur.

Aluminum sulphate (alum, Al2(SO4)3·nH2O) has successfully been used to reduce ammonia loss from poultry litter, cattle feedlots and manure composting, but has not yet been utilized in the thermal drying process of digestate solids. The objectives of the present study were to evaluate the effects of alum addition on ammonium nitrogen …
Consider the reaction when aqueous solutions of potassium hydroxide and ammonium sulfate are combined. The net ionic equation for this reaction is: Write a net ionic equation for the reaction that occurs when potassium sulfite (aq) and hydroiodic acid are combined. Note: Sulfites follow the same solubility rules as sulfates.
