What are the common uses of hydrochloric acid in chemistry
Hydrochloric acid has a great significance in industrial production of different goods, as a important laboratory reagent, as a cleaning agent and also in different organic and inorganic sectors.
The best five hydrochloric acid uses in chemistry
Hydrochloric acid uses as a very important organic reagent.
Hydrochloric acid uses in industry.
Hydrochloric acid uses in laboratory.
Hydrochloric acid uses in the preparation of pure NaCl.
Hydrochloric acid uses in daily life as a cleaning agent.
Other uses of hydrochloric acid.
Hydrochloric acid uses in laboratory
Hydrochloric acid is used as an important laboratory reagent. It is used to prepare hydrogen gas in laboratory.
Metals, such as, zinc, magnesium, iron, calcium etc which are electro-positive than hydrogen, react with dilute HCl and produced hydrogen gas. Hydrochloric acid is used as a group reagent.
A mixture of concentrated HCl acid and concentrated HNO 3 in 3:1 ratio,which is known as aqua regia, is used as a strong oxidizing agent.
Hydrochloric acid uses as a very important organic reagent
Hydrochloric acid is used as a reducing agent, catalytic reagent and a hydrolyzing agent in organic chemistry.
It is used in the preparation and identification of many important organic compounds.
For example, hydrochloric acid use in diazotization reaction for the preparation of chloro benzene from aniline .
Besides, it is used to prepare chloro ethane from alkene or alcohol, alkane from ketone etc.
Again, anhydrous ZnCl2 and concentrated HCl mixture [ known as Luis reagent], is used for identification of primary, secondary and tertiary aliphatic alcohol.
Hydrochloric acid uses in industry
Hydrochloric is used in industrial production of some important substance, such as metal chloride, chlorine, ammonium chloride and production of glucose from starch or from inversion of cane sugar etc.
Again, in galvanization process, HCl is used as a cleaning substance. It is used to clean iron sheet before tin plating or galvanization.
That is, for removal of iron oxide layer from the surface of iron sheet.
Most important use of HCl acid is in the dyeing industry, in the medicine production industry and in sugar industry.
The mixture of concentrated HCl acid and concentrated HNO3 in 3: 1 ratio, is used as a melting as well as refining agent in industry.
Hydrochloric acid uses in the preparation of pure NaCl
Hydrochoric acid is used to prepare pure sodium chloride from impure NaCl solution.The concentrated solution of NaCl is known as brine solution.
If a specific amount of HCl is added to this concentrated solution of HCl, then the pure NaCl is precipitated due to common ion effect.
Due to common Cl -ion, the solubility product of NaCl increases and hence pure NaCl is easily precipitated.
Hydrochloric acid uses in daily life as a cleaning agent
Other uses of hydrochloric acid.
Beside the above uses, hydrochloric acid is also used in industry for removal of lubricants from animal bone and also use for its purification.
HCl is used to prepare many organic compounds, such as alkyl chloride from alkene and alcohol and glucose, fructose from sugar.
