Reading 19.3
УдалитьThe Solubility Product Constant
Ionic compounds have widely differing solubilities. Sodium chloride has a solubility of about 360 g per liter of water at 25°C. Salts of alkali metals tend to be quite soluble. On the other end of the spectrum, the solubility of zinc hydroxide is only 4.2 × 10−4 g/L of water at the same temperature. Many ionic compounds containing hydroxide are relatively insoluble. The chapter Solutions, summarized a set of rules for predicting the relative solubilities of various ionic compounds in water.
Most ionic compounds that are considered to be insoluble will still dissolve, to a small extent, in water. These “mostly insoluble” compounds are still considered to be strong electrolytes because, essentially, any portion of the compound that dissolves will also dissociate into ions. As an example, silver chloride dissociate, to a small extent, into silver ions and chloride ions upon being added to water.
Константа продукта растворимости
Ионные соединения имеют широко различающиеся растворимости. Хлорид натрия имеет растворимость около 360 г на литр воды при 25 ° С. Соли щелочных металлов имеют тенденцию быть достаточно растворимыми. C другой стороны растворимость гидроксида цинка составляет всего 4,2 × 10–4 г / л воды при той же температуре. Многие ионные соединения, содержащие гидроксид, относительно нерастворимы. В главе «Решения» обобщен свод правил для прогнозирования относительной растворимости различных ионных соединений в воде.
Большинство ионных соединений, которые считаются нерастворимыми, все же будут в небольшой степени растворяться в воде. Эти «в основном нерастворимые» соединения по-прежнему считаются сильными электролитами, потому что, по существу, любая часть соединения, которая растворяется, также будет диссоциировать на ионы. В качестве примера, хлорид серебра в небольшой степени диссоциирует на ионы серебра и хлорид-ионы при добавлении в воду.
Listening
A civilized society is becoming more and more urbanized. More than 90% of people in industrialized countries now live and work indoors. We are moving further and further away from the natural world. Man needs not only land, forests, and minerals. Research shows that human individuality, emotional and spiritual well-being, and self-realization depend on our relationship with nature. Despite the technological advances of modern society, we are still closely connected to nature and need to find ways to bring it back into our lives to restore psychological balance. Even ordinary outdoor activities, such as gardening, walking with animals, or trips to the country, can have a beneficial effect on our state of mind.

Молекулярность реакции
ОтветитьУдалитьМолекулярность элементарной ступени - это общее число молекул реагента на этой ступени. На обеих стадиях механизма реакции, показанного выше, две молекулы реагента сталкиваются друг с другом. Это обе бимолекулярные реакции. Обратите внимание, что сталкивающиеся молекулы могут быть одинаковыми (как на этапе 1 выше) или разными (как на этапе 2 выше). Унимолекулярная стадия-это стадия, в которой в качестве реагента присутствует только одна молекула. Термолекулярная реакция включает в себя три реагирующие молекулы на одной элементарной стадии. Термолекулярные ступени относительно редки, поскольку они требуют одновременного столкновения трех молекул с достаточной энергией в правильной ориентации, что является редким событием. Когда термолекулярные реакции происходят, они имеют тенденцию быть очень медленными.
Законы и механизмы нормирования
Закон скорости реакции может быть определен из знания механизма реакции. Рассмотрим следующий мономолекулярная элементарная реакция:
