CHM130 Lesson 13 AYL

Explain the importance of buffer solutions as it relates to the pH of person's blood. If the pH value of blood remains in either alkaline or acidic form then it could prove harmful to a human being. It may even lead to death.
What is the difference between a strong acid and weak acid? What is the difference between a strong base and weak base? Give examples of each type. A strong acid is an acid which ionises almost completely when dissolved in water to produce a high concentration of hydrogen ions. A weak acid is an acid which partially ionises when dissolved in water to produce a low concentration of hydrogen ions.
What is the H3O+ and OH- concentration of the following solutions? Urine (pH = 6.0) Blood (pH = 7.4) Bile (pH = 8.0) Urine pOH = 1.00 x 10^-14/1.00 x 10^-6 = 1.00 x 10^-8 Blood pOH = 1.00 x 10^-14/3.98 x 10^-8 = 2.51 x 10^-7 Bile pOH = 1.00 x 10^-14/1.00 x 10^-8 = 1.00 x 10^-6
Cont..What is the H3O+ and OH- concentration of the following solutions? Urine (pH = 6.0) Blood (pH = 7.4) Bile (pH = 8.0) Urine [H3O+] = 10^-6.0 = 1.00 x 10^-6 M H3O+ Blood [H3O+] = 10^-7.4 = 3.98 x 10^-8 M H3O+ Bile [H3O+] = 10^-8.0 = 1.00 x 10^-8 M H3O+
