Chem 404 section 7 4-3-08 Acids, Bases, and pH Module 1 – Acid Strength 1. There is no relationship between pH and conductivity. A substance with low conductivity of 49 s a pH of 5.7 and a liquid with conductivity of 430 had a pH of 5.05. Logs are used instead of conductivity to show a more accurate relationship. 2. When acids are added to water generally the hydroium concentration in the system is increase lowering the pH making the solution more basic 3. HNO3 is a strong acid therefore completely dissociates in water, whereas a weak acid does not completely dissociate in water. Sulfuric acid, and HCL completely dissociate in water as well. HNO3 + H20 H3O+ + NO3- 4. Sulfuric acid is a little different than all other strong acids because sulfuric acid has the formula H2SO4 + H2O H3O+ + HSO4 and its conjugate pair is also an acid because it has one hydrogen that is able to donate to the systems. 5. All weak acids do not have the same strength because of their varying pH, although it is under 7 they have different concentrations of H3O+ ions that make them more and less strong. They are also good conductors of electricity. Module 2-Acid Concentration
