A buffer is made using 100.0 mL of 0.100 M CH;CH,COOH (propanoic acid) and 100.0 mL of 0.100 M NaCH;CH;COO (sodium propanoate). A) Explain in your own words what will occur (at the molecular level) when an nitric acid is added to the buffer? What would be the effect on the pH? B) Explain in your own words what will occur when LIOH is added tot he buffer? What would be the effect on the [H+1?
