Step 1
Which diagram represents the most concentrated weak acid?
Answer
To determine which diagram represents the most concentrated weak acid, we need to analyze the concentration of acid molecules, H⁺ ions, and anions in each diagram. A concentrated weak acid will have a higher number of acid molecules relative to the number of H⁺ ions and anions, implying that weak acids do not fully dissociate in solution.
- Evaluate Diagram A: Clearly shows fewer particles compared to the others, indicating a lower concentration.
- Evaluate Diagram B: Similar to Diagram A, with an even lower number of acid particles, which suggests a weaker solution.
- Evaluate Diagram C: This shows a moderate number of acid particles but still does not indicate a higher concentration compared to others.
- Evaluate Diagram D: This diagram displays the highest number of particles, suggesting it has the most concentrated weak acid.
Thus, the conclusion is that the diagram representing the most concentrated weak acid is Diagram D.
