(e) What is the percent dissociation in the solution of HZ?

검증된 단계별 안내

Identify the diagram corresponding to the solution of HZ. In this case, it is the third diagram from the left.

Count the total number of acid molecules (HA) initially present in the solution. This includes both dissociated and undissociated molecules.

Count the number of dissociated acid molecules (A- and H+ ions) in the solution.

Calculate the percent dissociation using the formula: \( \text{Percent dissociation} = \left( \frac{\text{Number of dissociated molecules}}{\text{Total number of molecules}} \right) \times 100 \% \).

Substitute the values obtained from steps 2 and 3 into the formula to find the percent dissociation.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Dissociation of Acids

Dissociation refers to the process by which an acid breaks apart into its constituent ions in solution. For weak acids, this process is not complete, meaning only a fraction of the acid molecules dissociate into ions. Understanding the extent of dissociation is crucial for calculating properties like pH and percent dissociation.

Percent Dissociation

Percent dissociation is a measure of how much of the original acid has dissociated into ions compared to the initial concentration. It is calculated using the formula: (amount dissociated / initial concentration) x 100%. This concept is important for understanding the strength of an acid and its behavior in solution.

Weak vs. Strong Acids

Acids are classified as strong or weak based on their ability to dissociate in water. Strong acids completely dissociate, while weak acids only partially dissociate. This distinction affects their pH, conductivity, and reactivity in chemical reactions, making it essential to identify the type of acid when analyzing solutions.
