Question

Определите степень диссоциации электролита,если в растворе находилось 500 молекул, а распались из них на 50 молекул.Каким будет данный электролит ?( сильным, слабым ,средним) ​

Answer 1

Объяснение:  

Степень диссоциации равна = количество диссоциированных молекул деленное на общее число молекул умноженное на 100%

α = $\frac{n}{N} * 100%$ , тогда

α = 50 / 500 = 0,1 = 10% - что является средним электролитом

(α > 30% - сильные

30% > α > 5% - средние

5% > α - слабые

α = 0 - неэлектролиты)

Ответ: 10%, средний

Answer 2

Determining the Degree of Dissociation of an Electrolyte

To determine the degree of dissociation of an electrolyte, we need to know the number of molecules that initially existed in the solution and the number of molecules that dissociated. In this case, we are given that there were 500 molecules in the solution and 50 of them dissociated.

The degree of dissociation (α) is defined as the ratio of the number of dissociated molecules to the total number of molecules initially present in the solution. Mathematically, it can be expressed as:

α = (Number of dissociated molecules) / (Total number of molecules initially present)

In this case, the degree of dissociation can be calculated as:

α = 50 / 500 = 0.1

Therefore, the degree of dissociation of the electrolyte is 0.1 or 10%.

Classification of the Electrolyte

The classification of an electrolyte as strong, weak, or moderate depends on its degree of dissociation.

- A strong electrolyte is one that completely dissociates into ions in solution. This means that the degree of dissociation (α) is close to 1 or 100%. Strong electrolytes include strong acids, strong bases, and soluble salts.

- A weak electrolyte is one that only partially dissociates into ions in solution. This means that the degree of dissociation (α) is less than 1 or 100%. Weak electrolytes include weak acids, weak bases, and slightly soluble salts.

- A moderate electrolyte is a term that is not commonly used in the classification of electrolytes. It is possible that the term was used in the context of a specific experiment or research study.

Based on the given information, the degree of dissociation of the electrolyte is 10%. Since the degree of dissociation is less than 100%, we can classify the electrolyte as a weak electrolyte.

Please note that the specific identity of the electrolyte is not provided in the question, so we cannot determine its exact nature or name.
