What is back titration

In direct titration methods, the analyte reacts directly with the titrant. To carry out analysis using this method, one working solution is sufficient.
Back titration methods (or, as they are also called, residue titration methods) use two titrated working solutions: a main and an auxiliary solution. For example, back titration of chloride ion in acidic solutions is widely known. First, a known excess of a titrated solution of silver nitrate (the main working solution) is added to the analyzed chloride solution. In this case, the formation reaction of slightly soluble silver chloride occurs: Ag+ + Cl- → AgCl. The excess amount of AgNO3 that has not reacted is titrated with a solution of ammonium thiocyanate (auxiliary working solution): Ag+ + SCN- → AgSCN. The chloride content can be calculated because the total amount of substance (mol) introduced into the solution and the amount of AgNO3 that did not react with the chloride are known.

Ammonium chloride, sulfate, ammonium carbonate, silver nitrate, barium chloride, sodium hydroxide, sulfuric acid, litmus. paper, chemical glassware for conducting experiments. March 21, 2012

As was said, the ammonium cation NH 4 plays the role of a metal cation and forms salts with acidic residues: NH 4 NO 3 - ammonium nitrate, or ammonium nitrate, (NH 4) 2 SO 4 - ammonium sulfate, etc.

All ammonium salts are crystalline solids, highly soluble in water. In a number of properties they are similar to alkali metal salts, and primarily to potassium salts, since the radii of the K + and NH + 4 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, forming characteristic precipitates. Ammonium carbonate reacts with acids because 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 (Fig. 133), for example:

or in ionic form:

Rice. 133.
Qualitative reaction to ammonium ion

This reaction is a qualitative reaction to ammonium salts, since the ammonia formed is easy to detect (in what ways can this be done?).

Laboratory experiment No. 31
Recognition of ammonium salts

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

This reaction also produces gaseous hydrogen chloride, which evaporates along with ammonia, and upon cooling combines with it again, forming a salt, i.e., when heated in a test tube, dry ammonium chloride sublimes, but on the cold walls of the upper part of the test tube it again settles in in the form of white crystals of NH 4 Cl (Fig. 134).

Rice. 134.
Sublimation of ammonium chloride

The main applications of ammonium salts were shown earlier (see Fig. 132).

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 absorb nitrogen only in bound form, that is, in the form of NH + 4 or NO - 3 ions. The remarkable Russian agrochemist D.N. Pryanishnikov found that if a plant has a choice, 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 NH 4 NO 3.

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

Ammonium chloride NH 4 Cl is used for soldering, as it cleans the metal surface of the oxide film and solder adheres well to it.

Ammonium bicarbonate NH 4 HCO 3 and ammonium carbonate (NH 4) 2 CO 3 are used in the manufacture of confectionery products, since these compounds easily decompose when heated and form gases that loosen the dough and make it fluffy:

Ammonium nitrate NH 4 NO 3 mixed with aluminum and coal powders is used as an explosive - ammonal, which is widely used in mining.

>> Chemistry: Ammonium salts

As was said, 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.

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

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

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

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

NH4Сl = NH3 + HCl

This reaction also produces gaseous hydrogen chloride, which evaporates along with ammonia, and upon cooling combines with it again, forming a salt, i.e., when heated in a test tube, dry ammonium chloride sublimes, but white crystals appear on the upper cold walls of the test tube again NН4Сl (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 absorb nitrogen only in bound form, that is, in the form of NH4 or N03 ions. The remarkable Russian agrochemist D.N. Pryanishnikov found that if a plant has a choice, 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 for soldering, as it cleans the metal surface of the oxide film and solder adheres well to it.

Ammonium bicarbonate NH4NC03 and ammonium carbonate (NH4)2CO3 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 NН4NO3 mixed with aluminum and coal powders is used as an explosive - ammonal, which is widely used in mining.
