When electricity is passed through a common salt solution, sodium hydroxide is produced along with the liberation of two gases ‘X’ and ‘Y’. ‘X’ burns with a pop sound whereas, ‘Y’ is used for disinfecting drinking water.
When electric current is passed through common salt solution the hydrogen gas is liberated at?
When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms. You might have expected sodium metal to be deposited at the negative electrode.
What is produced when electricity is passed through brine?
Complete answer: When electricity is passed through brine it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode. Sodium hydroxide solution is also formed near the cathode.
How are sodium hydroxide and cl2 gas produced from common salt What is this process called?
The process is called chlor-alkali process – because of the products fromed chlor for chlorine and alkali for sodium hydroxide. Chlorine gas is liberated at the anode and hydrogen gas at the cathode. Sodium hydroxide solution is formed near the cathode. The three products produced in this process are all useful.
When electric current is passed through aqueous solution of sodium chloride What happens?
When electricity is passed through an aqueous solution of sodium chloride, it gives hydrogen, chlorine and sodium hydroxide as a product. The balanced chemical equation is, This process is called as Electrolysis of Brine.
What happens when electricity is passed through salt water?
Electrolysis of an aqueous solution of table salt (NaCl, or sodium choride) produces aqueous sodium hydroxide and chlorine, although usually only in minute amounts. NaCl (aq) can be reliably electrolysed to produce hydrogen.
What is the formula of brine?
|Synonyms||Brine NaCl water HCl NaOH sodium chloride water water sodium chloride More…|
|Component Compounds||CID 313 (Hydrochloric acid) CID 962 (Water) CID 5360545 (Sodium)|
What happens when current is passed through body?
Electric current in the human body is dangerous for two primary reasons. First, it disrupts the normal operation of your nervous and muscular systems, causing severe muscle contractions. Second, just like in the light bulb, when current passes through your body, it’s transformed into thermal energy.
What is brine solution?
Brine, salt water, particularly a highly concentrated water solution of common salt (sodium chloride). Natural brines occur underground, in salt lakes, or as seawater and are commercially important sources of common salt and other salts, such as chlorides and sulfates of magnesium and potassium.
Is salt caustic?
Sodium chloride is one of the largest volume inorganic raw materials. Its major chemical products are caustic soda and chlorine. … Salt is also used as a flux in the production of aluminium.
Is salt a raw material?
Sodium chloride (salt) is one of the largest-volume inorganic raw materials used by the chemical industry. The major chemical downstream products of salt—chlorine/caustic and synthetic soda ash—are in turn used in the manufacture of many chemical products, both inorganic and organic.
Which of the following will not conduct electricity in aqueous solution?
Sugar solution does not form ion, hence it does not conduct electricity in aqueous solution.
When current is passed through a solution of NaCl?
When current is passed through molten NaCl i.e. sodium chloride, it decomposes into sodium and chlorine gas. Both sodium and chlorine gas move towards the electrode opposite to their own charge and either loses an electron or gains one.
Why does an aqueous solution of an acid conduct electricity?
Acids undergo dissociation in aqueous solution to form H+ ions. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.
