EXPLAIN: Why are pH and buffers important in biological systems?
As the pH increases, the solubility of which one of the following would increase?
**Please explain why that is the case or how the reaciton is taking place to understand why the solubility increases**

In an experiment to determine the amount of aspirin in a tablet, one of the
bottles of NaOH used was accidentally left open for 24 hours, which lead to
it reacting with carbon dioxide. What will be the effect on the calculated
amount of aspirin compared to the actual amount in the tablet and the
concentration of the NaOH solution?
Calculated amount increases since NaOH concentration will be lower than original.
Calculated amount increases since NaOH concentration will be higher than original.
Calculated amount decreases since NaOH concentration will be lower than original.
Calculated amount decreases since NaOH concentration will be higher than original.

- 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.
