1. List all the strong aqueous acids. What is the difference between a strong acid and a weak acid? How do the concentrations of the strong and weak acids compare to the H3O+ in solution? You don't need to list all of the strong aqueous acids. I am guessing strong acid has more hydrogen ions? 2. What is pH? What happens to pH as the [H3O+] increases? Support your answer by comparing the pH of 0.50 M and 0.050 M HCl. For this one I know ph is the measurement of the acidity/baic of the solution 3. Why is the pH of basic solution greater than 7.0 while that of acids is less than 7.0? Would the pH of a 0.1 M weak acid be greater than or less than that of a 0.1 M strong acid ? 4. If the measured pH of a 0.10 M weak acid, HA, is 2.45, what is its experimental Ka value. 5. Give examples of a neutral salt, acidic salt and basic salt. Explain your choice.
