Chapter 16, Problem 43
The three diagrams represent three different solutions of the binary acid HA. Water molecules have been omitted for clarity, and hydronium ions (H3O+) are represented by hydrogen ions (H+). Rank the acids in order of decreasing strength.
Verified step by step guidance1
<Identify the components in each diagram: HA molecules, H+ ions, and A- ions.>
<Understand that the strength of an acid is determined by its ability to donate protons (H+ ions).>
<For each diagram, count the number of H+ ions and compare it to the number of HA molecules.>
<The more H+ ions present relative to HA molecules, the stronger the acid, as it indicates more dissociation.>
<Rank the acids based on the ratio of H+ ions to HA molecules, from highest to lowest ratio, indicating decreasing acid strength.>
