what are the different functions of hydrochloric acid?

Stomach secretions are made up of hydrochloric acid, several enzymes, and a mucus coating that protects the lining of your stomach. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. It also eliminates bacteria and viruses in the stomach, protecting your body from infection.

Hypochlorous acid is one of the most effective known biocides. This weak acid with the chemical name HClO or HOCl is the same chemical produced by the human immune system to kill invasive organisms and fight infection.

When HCl is dissolved in water, ions of H and Cl are formed. Hydrogen loses an electron (becoming an ion of +1 charge) and chlorine gains an electron (becoming an ion of -1 charge). Strong acids, like HCl, release many more hydrogen ions in water than do weak acids, like vinegar or lemon juice.

The key difference between sodium hypochlorite and hypochlorous acid is that sodium hypochlorite contains a sodium cation and hypochlorite anion, whereas hypochlorous acid contains a proton and hypochlorite anion. Both sodium hypochlorite and hypochlorous acid contain anions made of oxides of chlorine.

HCl is a strong electrolyte and when it dissolves in water it separates almost completely into positively - charged hydrogen ions and negatively - charged chloride ions. This aqueous solution is usually called hydrochloric acid.

The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.

To find the number of moles of H+ in this beaker, you would have to know how many H+ ions are in each mole of hydrochloric acid (HCl), and multiply it by the number of moles of HCl present in the beaker: 1 mole of HCl = 1 mole of H. 2 moles of HCl = 2 moles of H.

In the following list of acids, separate strong acids from weak acids: Hydrochloric acid, citric acid, acetic acid, nitric acid, formic acid, sulphuric acid. Answer: In aqueous solutions, strong acids ionise completely and provide hydronium ions. ... Strong acids —>Hydrochloric acid, sulphuric acid, nitric acid.

Hydrochloric acid, HCl(aq), is a strong acid. Sodium hydroxide, NaOH(aq), is a strong base. NaCl(aq) is a neutral solution.

Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. A weak acid is an acid that ionizes only slightly in an aqueous solution. ... Weak acids, like strong acids, ionize to yield the H + ion and a conjugate base. Because HCl is a strong acid, its conjugate base (Cl − ) is extremely weak.

A solution of 0.8 mol/dm 3 hydrochloric acid has a pH of 0.1. Predict its pH when it is diluted to 0.08 mol/dm 3. The hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 from 0.1 to 1.1.

It consists of non-corrosive and non- reactive chloride ion. The physical properties like boiling and melting points, density, and pH, of hydrochloric acid, varies depending on the concentration of hydrochloric acid in water. It is colorless with a highly pungent odor. HCl is a strong acid.

Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then aids digestion by breaking the amino acid bonds, a process called proteolysis. In addition, many microorganisms are inhibited or destroyed in an acidic environment, preventing infection or sickness.
