Question

Дать определение слабого электролита с точки зрения теории электролитической диссоциации. Привести примеры.

Answer 1

Ответ:

Понятие электролитов и неэлектролитов впервые ввёл еще М. Фарадей в первой половине 19 века. С точки зрения ТЭД электролиты - это вещества, растворы или расплавы которых проводят электрический ток. Электролитами являются вещества с сильно полярной ковалентной или ионной связью.  К ним относятся соли, щёлочи, кислоты.
Неэлектролитами являются вещества с неполярными или слабополярными ковалентными связями.

Это большинство органических соединений - глюкоза, фруктоза, сахароза, этанол, глицерин, простые вещества-неметаллы - сера, алмаз, азот, кислород и др.

Definition of a Weak Electrolyte from the Perspective of Electrolytic Dissociation Theory

According to the theory of electrolytic dissociation, a weak electrolyte is a substance that only partially dissociates into ions when dissolved in a solvent, such as water. This means that in a solution of a weak electrolyte, only a fraction of the molecules break apart into ions, while the rest remain in their molecular form.

Examples of Weak Electrolytes

1. Acetic Acid (CH3COOH): Acetic acid is a weak electrolyte because it only partially dissociates into ions when dissolved in water. In an aqueous solution of acetic acid, only a small fraction of the molecules dissociate into acetate ions (CH3COO-) and hydrogen ions (H+), while the majority of the molecules remain as undissociated acetic acid.

2. Ammonia (NH3): Ammonia is another example of a weak electrolyte. When dissolved in water, only a small portion of the ammonia molecules dissociate into ammonium ions (NH4+) and hydroxide ions (OH-), while the majority of the ammonia molecules remain in their molecular form.

3. Carbonic Acid (H2CO3): Carbonic acid is a weak electrolyte that forms when carbon dioxide dissolves in water. In an aqueous solution of carbonic acid, only a fraction of the carbonic acid molecules dissociate into hydrogen ions (H+) and bicarbonate ions (HCO3-), while the majority of the molecules remain as undissociated carbonic acid.

It's important to note that weak electrolytes conduct electricity to a lesser extent compared to strong electrolytes, which fully dissociate into ions when dissolved in a solvent. Weak electrolytes are commonly used in various chemical and biological processes, and their partial dissociation behavior is crucial for understanding their properties and behavior in solution.
