Consider the below statements and identify the correct answer. Statement- I: Human stomach produces nitric acid. Statement-II: Hydrochloric acid helps in the digestion of food without harming the stomach.

Correct option is A

The correct answer is (a) Only Statement II is correct.

Analyze both statements:

Statement I: Human stomach produces nitric acid.

• This statement is incorrect. The human stomach produces hydrochloric acid (HCl), not nitric acid. Hydrochloric acid aids in digestion by creating an acidic environment that helps break down food and kill bacteria.

Statement II: Hydrochloric acid helps in the digestion of food without harming the stomach.

• ​This statement is correct. Hydrochloric acid plays a crucial role in digestion by breaking down food and activating digestive enzymes. The stomach lining is protected by a layer of mucus, which prevents the acid from damaging the stomach tissue.

Information booster:

• Hydrochloric Acid (HCl)
  
• Chemical Formula: HCl
• Appearance: A colorless or slightly yellow liquid with a pungent odor.
• Uses: Essential in many industrial processes, including the production of chlorides, fertilizers, and dyes. Also used for pH control and in food processing.
• Role in Digestion: In the stomach, hydrochloric acid helps break down food and activates digestive enzymes, such as pepsin, which aid in protein digestion.
• pH Level: Very acidic, with a pH of around 1-2, which is necessary for the digestive processes in the stomach.
