Question:

Pancreatic juice is composed of several digestive enzymes as well as a high concentration of bicarbonate ions, making it an alkaline solution. Since the pH of this fluid is high (not acidic), it is unlikely that it would increase the acidity of the stomach.
Due to the various digestive enzymes, pancreatic juice does break down carbohydrates and proteins. And due to its high pH, it neutralizes the acidity of stomach chyme.
