When electricity is passed through sodium chloride (NaCl) in a process called electrolysis, the compound breaks down into its component elements: sodium (Na) and chlorine (Cl). Sodium ions migrate towards the negative electrode (cathode) and gain electrons to form sodium metal, while chloride ions migrate towards the positive electrode (anode) and lose electrons to form chlorine gas.

What happens when electricity is passed through aqueous solution of sodium chloride?
When electricity is passed through an aqueous solution of sodium chloride (saltwater), a process called electrolysis occurs. The water molecules in the solution are split into hydrogen and oxygen gases at the cathode and anode, respectively, while the sodium and chloride ions in the solution migrate towards the oppositely charged electrodes. This process results in the production of hydrogen gas, chlorine gas, sodium hydroxide, and additional byproducts depending on the specific conditions.
Why will molten Sodium Chloride undergo electrolysis?
Molten sodium chloride undergoes electrolysis because it allows the ions to freely move and conduct electricity. When an electric current is passed through the molten sodium chloride, sodium ions are attracted to the negative electrode (cathode) and gain electrons to form sodium atoms, while chloride ions are attracted to the positive electrode (anode) and lose electrons to form chlorine atoms. This process separates the sodium and chlorine, leading to the production of sodium metal and chlorine gas.
What happens when chlorine gas is passed through calcium hydroxide?
When chlorine gas is passed through calcium hydroxide, it reacts to form calcium hypochlorite, calcium chloride, and water. The chemical equation for this reaction is: 2Ca(OH)2 + 2Cl2 → Ca(ClO)2 + CaCl2 + 2H2O. This is a common method used to produce calcium hypochlorite, which is commonly used as a bleaching agent and disinfectant.
How you would break down sodium chloride into its constituent elements?
Sodium chloride (table salt) can be broken down into its constituent elements sodium and chlorine through a process called electrolysis. When an electric current is passed through molten sodium chloride, the sodium ions (Na+) are attracted to the negative electrode (cathode) and gain electrons to form sodium metal, while the chloride ions (Cl-) are attracted to the positive electrode (anode) and lose electrons to form chlorine gas.
How can you prepare sodium hydroxide by diaphragm cell commercially?
To prepare sodium hydroxide by a diaphragm cell commercially, a brine solution (sodium chloride in water) is fed into the anode compartment. An electrical current is passed through the cell, causing chloride ions to move towards the anode and undergo oxidation to form chlorine gas. The sodium ions move through the diaphragm to the cathode compartment, where they react with water to produce sodium hydroxide.
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
What happens when dry HCl gas is passed through saturated solution of sodium?
When dry HCl gas is passed through a saturated solution of sodium chloride (NaCl), no visible reaction occurs. The sodium chloride remains dissolved in the water, as HCl gas does not react with NaCl in this situation.
What happens when electricity is passed through aqueous solution of sodium chloride?
When electricity is passed through an aqueous solution of sodium chloride (saltwater), a process called electrolysis occurs. The water molecules in the solution are split into hydrogen and oxygen gases at the cathode and anode, respectively, while the sodium and chloride ions in the solution migrate towards the oppositely charged electrodes.

What is a metal that glows when electricity is passed through it?
Phosphorus is a non-metal that glows when electricity is passed through it. It emits a light known as phosphorescence.
What has a reddish orange glow when electricity is passed through it?
Neon gas displays a reddish-orange glow when electricity is passed through it, commonly seen in neon lights.
How is electricity transferred from batteries to the light bulb?
Electricity is passed through a wire from battery to bulb
What happens to the concentration of sulphuric acid as the electricity is passed through it?
the h2 ions and the so4 ions in the sulphuric acid help electricity pass through it. this makes it a strong electrolyte.(electrolyte- a liquid which conducts electricity)
What happens when chlorine is passed through boiling toluene?
Electrophilic halogenation
What do you observe when ethyne is passed through ammoniacal cuprous chloride solution?
When ethyne is passed through ammoniacal cuprous chloride solution, the blue color of the cuprous chloride solution fades as the ethyne reduces cuprous chloride to copper, forming reddish-brown copper. This reaction is a test for unsaturation in organic compounds.
Why did each gas only show a color when electricity was passed through it?
When electricity is passed through a gas, it causes the gas atoms or molecules to become excited and emit light at specific wavelengths. Each gas has a unique set of energy levels, so when electricity is passed through it, the emitted light will reveal the characteristic color associated with that specific gas.
What is the isolation of sodium?
Sodium is isolated through the electrolysis of molten sodium chloride (NaCl) in the Downs process. In this process, electricity is passed through the molten NaCl, causing sodium ions to be reduced at the cathode to form metallic sodium. The sodium then floats to the surface and is collected.
What happens when hydrogen chloride is passed into ammonia?
When hydrogen chloride is passed into ammonia, the two compounds will react to form a white solid compound called ammonium chloride. This reaction is a classic example of a neutralization reaction, where an acid reacts with a base to form a salt and water.
