The substance that shows increased solubility as the pH of the solution becomes more acidic is to be identified from the exercise 27 and 28 . The equations for the chemical reactions that occur to increase the solubility are to be stated. Concept introduction: The solubility of salt is affected by pH . The decrease in the value of pH has the opposite effect that is based on the application of Le Chatlier’s principle. The anions of strong acid and their salt is independent of pH value whereas anions of weak acid is affected by pH value. If the pH value of basic salt is decreased, its solubility will increase.

1. Copper oxides are a product of the oxidation of copper that often form on the inside of copper pipes transporting water and serves to protect the pipes against corrosion. They are toxic. At a pH above 8, these oxides are virtually insoluble in water. As the pH of the water flowing drops below 7, the solubility of these oxides increases, and the layer begins to dissolve. Based on this knowledge, and the data collected in your lab, what implications does this have on toxic metal pollutants or other pollutants in our drinking supply when the water flowing is acidic? Would this problem become better or worse if the water flowing through the pipes was hot? 2. The chemical obtained from red cabbage that acts as a pH indicator is a pigment called anthocyanin. Based on your results, do you think anthocyanin is a useful indicator? Why or why not?

Equimolar quantities of potassium fluoride and hydrofluoric acid are placed into solution. What happens to the buffer system if some hydrochloric acid is added to the solution? The hydrochloric acid reacts with the fluoride ions so the pH decreases only slightly. The hydrochloric acid reacts with the fluoride ions so the pH decreases significantly. ) The hydrochloric acid reacts with the hydrofluoric acid so the pH increases only slightly. The hydrochloric acid reacts with the hydrofluoric acid so the pH increases significantly.
