please explain the process and answer Mouthwash acts to clean and disinfect mouths. Two important considerations when designing a mouthwash solution are the pH, which should ideally not be too acidic (where saliva has a normal pH range of 6.2–7.6 and below pH 5.5 erosion may occur), and the resistance of the solution to changes in pH. One example of a buffering system used in mouthwash is based on the compound H3PO4 which has PKa values of 2.1, 7.2 and 12.3. i. Hand-draw the structure of the main phosphorus species at pH 7.0, as well as a balanced equilibrium equation showing the structures of the two main phosphoric acid species at pH 7.0.

Lakes have a natural buffering capacity, especially in regions where limestone gives rise to dissolved calcium carbonate. Write an equation for the effect of a small amount of acid rain containing sulfuric acid if it falls into alake containing carbonate (CO3-2 ) ions. Discuss how the lake will resist further pH changes. What happens if a large excess of acid rain is deposited?
You are in charge of making a phosphate buffer at pH 7.5. You are out of solid versions of phosphate,but you find stock solutions of 1.0 M NaH2PO4 and 1.0 M Na2HPO4 in the lab and decide to make thebuffer with these solutions. How much of each of the stock solutions would you mix together to make 200mL of 1.0 M phosphate buffer at pH 7.5? (The pKa values of phosphoric acid are 2.1, 7.2, and 12.3.)
The Ka values for nitrous acid (HNO2) and hypochlorous (HClO) acid are 4.5 * 10-4 and 3.0 * 10-8, respectively. Which one would be more suitable for use in a solution buffered at pH = 7.0? What other substances would be needed to make the buffer?
6 A phosphate buffer is prepared of pH = 8.0 using NaH2PO4 and NaOH. After mixing and adjusting the pH to 8.0, the total concentration of all phosphorous containing species is 0.200 M. Calculate the concentrations of all of the species present in the buffer solution.
