How is the degree of ionization of an acid related to its pH? The lower the pH, the higher the concentration of hydrogen ions. The lower the pKa, the stronger the acid and the greater its ability to donate protons is. 3. Antacids neutralize stomach acids. Using a suitable equation, explain how an antacid works. 3HCl + AL(OH)3 3H2O + AlCl3 o Antacids are used to neutralize excess stomach acid (HCL). In this equation, you see the mixture of aluminum hydroxide, which is not very soluble being added to the stomach acid to produce water and aluminum chloride . 4. Explain what is meant by “Buffer”. What is the pH of blood? Using suitable equations, explain how the blood buffering system works A buffer solution maintains the pH of a solution by neutralizing small amounts of added acid or base. Blood plasma contains buffers that maintain a consistent pH of about 7.4. This means that the blood is naturally slightly alkaline/basic. o HC2H3O2 + H2O H3O+ + C2H3O2- This buffer I made from a weak acid and a salt. The weak acid (acetic acid) dissociates slightly in water to form G3O+ and a small amount of C2H3O2-. The addition of its salt, sodium acetate, provides a much larger concentration of acetate ion, which is necessary for its buffering capability.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
