Additionally, the liver also contributes bile salts to the duodenum, which further helps to alkalize the chyme.

Why the medium in stomach is acidic while that in intestine is basic?

This conversion from acidic to alkaline pH is due to the actions of bile, which is relased on to the partially digested food in the duodenum.

Why does fat not begin to decrease immediately after entering the duodenum?

Fats need to be emulsified by bile before lipase can act on it. Lipase also needs an alkaline medium to act well and acid in the food from the stomach must first be neutralised before lipase can act on it.
