1.	The pH value of gasfric juice in humna stomach is about 1.8 and in intiestine , it is about 7.8. The `pk_(a)` value of aspirin is 3.5 Aspirin will beA. ionised in the small intestine and almost unionised in the stomachB. unionised in the small intestine and in the stomachC. completelyl ionised in the small intestine and in the stomachD. ionised in the stomach and almost unionised in the amall intestine
Answer» Correct Answer - A Aspirin is a moderate acid (`pk_(a) = 3.5 `) hence it is almost unionised in stomach due to its strong acidie medium because of HCl. It is due to common ion effect while in small intestine, the medium is alkaline, hence aspirin will be sufficiently ionised in small intestine.
