The chapter refers to a general concept of solubility product Ksp of sparingly soluble hydroxides and different salts and calculation of solubility of some hydroxides, oxides, and different salts in aqueous media. An indisputable advantage of the latter approach is proved in simulation of static or dynamic, two-phase nonredox or redox systems. The problem of solubility of various chemical compounds occupies a prominent place in the scientific literature. This stems from the fact that among various properties determining the use of these compounds, the solubility is of the paramount importance. Among others, this issue has been the subject of intense activities initiated in by the Solubility Data Commission V.

18.2: Relationship Between Solubility and Ksp

The development of learning module of solubility and solubility product topic for Standard International School SBI and Pioneer of Standard International School RSBI students is very interesting to be discussed and implemented, because educational issues in Indonesia facing the low quality of education at every level and educational unit. It is important, to get good and standard chemistry module in order to be used as learning media on the teaching of Solubility and Solubility Product for SBI and RSBI students that can increase student achievement that effective implemented to Senior High School students compared with textbook as media. The procedure is done trough analyzing of four bilingual textbooks, then the development of learning module that standardize by the lecturers, teachers, and students and then doing trial of module for students. From the data of the instrument threre are 20 from 30 item test that are valid with rcount 0. The result of the using of learning module in class can increase student achievement by seeing the average of high group learning outcomes in experiment class is For low group, average of students achievement, experiment class From the result of hypothesis testing, for low group tcount 2.

This page is a brief introduction to solubility product calculations. These are covered in more detail in my chemistry calculations book. I am going to assume that you are given the solubility of an ionic compound in mol dm If it was in g dm -3 , or any other concentration units, you would first have to convert it into mol dm The solubility of barium sulphate at K is 1. Calculate the solubility product.

We've seen many ionic compounds. Many are soluble in water and many are not. There is no simple set of rules which we can use to predict which ones will be soluble or not. Reactions where soluble compounds react to form insoluble ones are called precipitation reactions. The reverse is a dissolution reaction where solid compounds dissolve upon addition into water. Since salts dissolve into electrically charged species as do acids and bases they fall in the general category called electrolytes. We saw in the case of acids and bases that some dissociate completely into ions and are called strong while others dissociate only partially and are called weak.

In this article, we shall study the concept of solubility, solubility product, and its applications. Some ionic solids are highly soluble in water while others are almost insoluble in it. The solubility of ionic solid depends on lattice enthalpy of the salt and hydration enthalpy of ions in solution. The lattice enthalpy of salt is defined as the energy required to overcome the attractive forces between the ions. It is always positive. The hydration enthalpy or solvation enthalpy is the energy released during the interaction between the ions and solvent molecules.

Among others, this issue has been the subject of intense activities initiated in by the Solubility Data Commission V. Within —, the series of 87 volumes, concerning the solubility of gases, liquids, and solids in liquids or solids, were issued [ 3 ]; one of the volumes concerns the solubility of various oxides and hydroxides [ 4 ].


taken as an example. Solubility products refer to a large group of sparingly soluble salts and hydroxides and some. oxides, e.g., Ag.

View Summary17Solubility. When a slightly soluble ionic compound is added to water, some of it dissolves to form a saturated solution, establishing an equilibrium between the pure solid and a solution of its ions. Solubility products present a rich opportunity to discuss solubility qualitatively, but the opportunity is seldom used.

It is relevant in saturated solutions in which an ionic compound has not fully dissolved.

Каждый новый шифр после его вскрытия переводится на безопасное хранение из шифровалки в главную базу данных АНБ по оптико-волоконному кабелю длиной 450 ярдов. В это святилище существует очень мало входов, и ТРАНСТЕКСТ - один из. Система Сквозь строй должна служить его верным часовым, а Стратмору вздумалось ее обойти. Чатрукьян слышал гулкие удары своего сердца. ТРАНСТЕКСТ заклинило на восемнадцать часовМысль о компьютерном вирусе, проникшем в ТРАНСТЕКСТ и теперь свободно разгуливающем по подвалам АНБ, была непереносима. - Я обязан об этом доложить, - сказал он вслух.

 Откуда вам это известно. - Это не имеет отношения к делу. Нуматака выдержал паузу. - А если мистер Беккер найдет ключ. - Мой человек отнимет .

 Вам нужно знать только одно: он будет найден. - Откуда такая уверенность. - Не я один его ищу. Американская разведка тоже идет по следу. Они, вполне естественно, хотят предотвратить распространение Цифровой крепости, поэтому послали на поиски ключа человека по имени Дэвид Беккер. - Откуда вам это известно.

Беккеру не хотелось так быстро уходить от алтаря, но когда две тысячи людей ждут причастия, а обслуживают их всего восемь священнослужителей, было бы неприличным медлить с этим священным глотком.

 - Позволь мне объяснить.  - Голос его, однако, мягче не.  - Во-первых, у нас есть фильтр, именуемый Сквозь строй, - он не пропустит ни один вирус.

However, this article discusses ionic compounds that are difficult to dissolve; they are considered "slightly soluble" or "almost insoluble.

So, Ksp(AgCR) is the solubility product constant for AgCR, when it dissolves (or tries to!) according to the above equation. • Like most Keq's, its value depends on T.
