>> Chemistry: Ammonium salts

As mentioned, the ammonium cation NH4 + plays the role of a metal cation and it forms salts with acidic residues: NH4NO3 - ammonium nitrate, or ammonium nitrate, (NH4) 2SO4 - ammonium sulfate, etc.

All ammonium salts are crystalline solids, readily soluble in water. In a number of properties, they are similar to alkali metal salts, and primarily to potassium salts, since the radii of K+ and NH+ ions are approximately equal.

Ammonium salts are obtained by reacting ammonia or its aqueous solution with acids.

They have all the properties of salts due to the presence of acidic residues. For example, ammonium chloride or sulfate reacts with silver nitrate or barium chloride, respectively, to form characteristic precipitates. Ammonium carbonate reacts with acids as the reaction produces carbon dioxide.

In addition, the ammonium ion causes another property common to all ammonium salts: its salts react with alkalis when heated to release ammonia.

This reaction is a qualitative reaction for ammonium salts, since the resulting ammonia is easily detected (how exactly?).

The third group of properties of ammonium salts is their ability to decompose when heated to release gaseous ammonia, for example:

NH4Cl = NH3 + HCl

In this reaction, gaseous hydrogen chloride is also formed, which volatilizes along with ammonia, and when cooled, recombines with it, forming a salt, i.e., when heated in a test tube, dry ammonium chloride seems to sublime, but white crystals appear again on the upper cold walls of the test tube NH4Cl (Fig. 32).

The main areas of application of ammonium salts were shown earlier, in Figure 31. Here we draw your attention to the fact that almost all ammonium salts are used as nitrogen fertilizers. As you know, plants are able to assimilate nitrogen only in a bound form, i.e., in the form of NH4 or NO3 ions. The remarkable Russian agrochemist D. N. Pryanishnikov found out that if a plant has a choice, then it prefers the ammonium cation to the nitrate anion, so the use of ammonium salts as nitrogen fertilizers is especially effective. A very valuable nitrogen fertilizer is ammonium nitrate NH4NO3.

Let us note other areas of application of some ammonium salts.

Ammonium chloride NH4Cl is used in soldering, as it cleans the metal surface from the oxide film and solder adheres well to it.

Ammonium bicarbonate NH4NC03 and ammonium carbonate (NH4)2C03 are used in confectionery, as they easily decompose when heated and form gases that loosen the dough and make it fluffy, for example:

NH4HC03 = NH3 + H20 + CO2

Ammonium nitrate NH4NO3 mixed with aluminum and coal powders is used as an explosive - ammonal, which is widely used in the development of rocks.

What is back titration

In direct titration methods, the analyte reacts directly with the titrant. For analysis by this method, one working solution is sufficient.
In back titration methods (or, as they are also called, residue titration methods), two titrated working solutions are used: the main and auxiliary. It is widely known, for example, the back titration of the chloride ion in acidic solutions. To the analyzed solution of chloride, first add a deliberate excess of a titrated solution of silver nitrate (basic working solution). In this case, the reaction of the formation of poorly soluble silver chloride occurs: Ag + + Cl- → AgCl. The excess amount of AgNO3 that has not entered into the reaction is titrated with an ammonium thiocyanate solution (auxiliary working solution): Ag+ + SCN- → AgSCN. The chloride content can be calculated, since the total amount of the substance (mol) introduced into the solution and the amount of the AgNO3 substance that did not react with chloride are known.
