Expert Solution
Step 1

The question asked to rank the given solutions from highest to lowest pH, which required an understanding of the relative strengths of acids and bases and their effect on the pH of the solution. The pH scale ranges from 0 to 14, with 7 being neutral, values less than 7 being acidic, and values greater than 7 being basic or alkaline. Strong acids and bases have a more significant impact on the pH than weak acids and bases, and the concentration of the solution also affects its pH. By considering these factors, the given solutions were ranked in the order of their pH, with the highest pH at the top and the lowest pH at the bottom of the list.
