What is the main function of hydrochloric acid?

Hydrochloric acid is the main component of the gastric juices produced in the stomach and it maintains the stomach pH of 1 to 2 by acidifying the stomach contents. Hydrochloric acid acts as a barrier against foreign microorganisms and helps prevent infection.

What is the function of HCl Class 10?

The HCL present in the gastric juice dissolves bits of food and creates an acidic medium in our stomach. The enzyme pepsinogen is converted to pepsin in this acidic medium. Pepsinogen is a protein-digesting enzyme. It also kills bacteria and other microorganisms that enter along with the food in our stomach.

What is the function of acid?

Explanation: Acids play important roles in the human body. The hydrochloric acid present in the stomach aids digestion by breaking down large and complex food molecules. Amino acids are required for synthesis of proteins required for growth and repair of body tissues.

What is the function of HCl in digestion where is it secreted from?

HCl is one of the gastric juices secreted by stomach. HCl converts the inactive enzyme pepsinogen into its active form pepsin. Pepsin digests proteins and breaks them into amino acids. HCl also kills harmful pathogens or particles in our food when it reaches the stomach through the gastrointestinal duct.

What is the function of hydrochloric acid Class 7?

Hydrochloric acid is an essential acid in the stomach. It helps destroy bacteria, as well as other harmful species. It also works as a preservative for food. HCl converts pepsinogen which is not active into pepsin to metabolize proteins in our stomach.

What is the function of hydrochloric acid in stomach Mcq?

It creates the acidic conditions necessary for the action of the enzyme pepsin. It activates pepsin to act on proteins. It also destroys the structure of proteins so that the enzymes can digest them easily. It gets mixed with food and kills the bacteria present in food.

What is the role of acid in the stomach Class 10?

It creates a medium of gastric juice acidic so that the enzyme pepsin digests the protein and kills the bacteria present in them. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The acid activates the pepsinogen enzyme required to digest proteins.

What is the pH of hydrochloric acid?

1.5 to 3.5
Hydrochloric acid is an essential component of gastric acid, which has a normal pH of 1.5 to 3.5. A weak acid or base does not ionize completely in aqueous solution.

What is the function of HCl secreted in the stomach Brainly?

What is the function of acid in human body?

Acids play important roles in the human body. The hydrochloric acid present in the stomach aids digestion by breaking down large and complex food molecules. Amino acids are required for synthesis of proteins required for growth and repair of body tissues.

What is the role of acid in our stomach answer?

Stomach acid, or gastric acid, is a watery, colorless fluid that’s produced by your stomach’s lining. It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract.

How do you calculate the pH of HCl?

To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH.

What is the pH value of HCl?

The usual range of pH values encountered is between 0 and 14, with 0 being the value for concentrated hydrochloric acid (1 M HCl), 7 the value for pure water (neutral pH), and 14 being the value for concentrated sodium hydroxide (1 M NaOH).

What is the pH level of hydrochloric acid?

The pH of hydrochloric acid is 0, which means that it has the highest degree of acidity on the pH scale. Hydrochloric acid is a clear and highly corrosive solution of hydrogen chloride in water.
