Answer to Question 1

A

Answer to Question 2

Taking aspirin automatically lowers pH in the stomach, as would ingesting any acidic substance. The gimmick behind buffered aspirin is to package in a tablet both the aspirin (the acid) and a solid mixture of compounds which form a buffer when dissolved in the stomach. The buffer action tends to resist the change in pH brought about by ingesting the aspirin, and thus minimize any stomach upset.
