Verified step by step guidance

Step 1: Understand the concept of acid strength. Acid strength is determined by the degree of ionization in water. A strong acid completely ionizes, while a weak acid only partially ionizes.

Step 2: Analyze the illustrations. Each illustration represents a solution with molecules depicted as black and white circles. The black circles represent the undissociated acid molecules, and the white circles represent the dissociated ions.

Step 3: Compare the number of dissociated ions (white circles) to the undissociated molecules (black circles) in each illustration. The illustration with the fewest white circles relative to black circles represents the weakest acid.

Step 4: Identify the illustration with the least number of dissociated ions. This illustration will have more black circles compared to white circles, indicating less ionization and therefore a weaker acid.

Step 5: Conclude which illustration represents the weakest acid based on your analysis. The illustration with the highest proportion of undissociated molecules (black circles) is the weakest acid.
