pH of gastric juice in stomach is vary from 1.5 - 3.5. So it could be 2.

Explanation:

Gastric juice present in the stomach is acidic in nature. It is composed of mainly sodium chloride, hydrochloric acid and potassium chloride. It is produce by the cells present in stomach lining. It activate the digestive enzyme and play important role in the digestion of protein . These enzymes break the chain of amino acids. Its acidic pH is not harmful for the stomach because lining cells of stomach also produce mucus that act as a barrier.

Hydrochloric Acid:

HCl is secreted by parietal cells of stomach. it kills the pathogens and bacteria in food and also convert the pepsinogen into pepsin. pepsin breaks the secondary and tertiary proteins and help in digestion.

Pepsinogen:

It also help to digest the protein.

Hormones and Electrolytes:

They help in food digestion and nutrient absorption.

Gastric Lipase:

t help to breake the fats of short and medium chain.
