What else can I help you with?
What is the gas evolved at anode during electrolysis of aqueous NaCl?
Chlorine gas is evolved at the anode during the electrolysis of aqueous sodium chloride (NaCl) because chloride ions are oxidized to form chlorine gas.
Can you separate hydrogen in the sodium chloride solution?
NaCl itself will not render any hydrogen, however you can separate hydrogen from the water through the process of electrolysis. During electrolysis of NaCl solution, hydrogen will be evolved at cathode.
What term do you use to indicate salt solution in water in a chemical reaction?
(aq) It means aqueous. Example: NaCl(aq)
What is the correct way to show sodium chloride in aqueous solution?
To show sodium chloride in aqueous solution, you would write it as NaCl(aq), where (aq) denotes that it is dissolved in water. This indicates that sodium chloride has dissociated into its respective ions, Na+ and Cl-, in the aqueous solution.
Is chlorine extracted from electrolysis?
Yes, it is a primary way to extract chlorine gas.The most common means is to use electrolysis in a tank containing a solution of potassium chloride (KCl) or sodium chloride (NaCl, better known as table salt). The end result is potassium/sodium hydroxide in the solution--either one a very useful strong base, hydrogen gas, and chlorine gas.
Why Na ion and OH- ion not combine in electrolysis of aqueous NaCl?
They actually do combine during electrolysis of aqueous Sodium Chloride
Why do you use molten NaCl in electrolysis instead of an aqueous solution of NaCl?
Molten NaCl is preferred over an aqueous solution of NaCl in electrolysis because in the molten state, NaCl dissociates into Na+ and Cl- ions without the presence of water molecules, allowing for direct electron transfer at the electrodes. In an aqueous solution, water molecules also undergo electrolysis, leading to the production of hydrogen gas and oxygen gas, which can interfere with the desired reactions involving Na+ and Cl- ions. Additionally, the high melting point of NaCl ensures that it remains in the molten state during the electrolysis process, providing a stable environment for the reactions to occur.
Why sodium chloride is not in the aqueous state?
The reduction potential of sodium is under the same potential of water.
How is the electrolysis different when the sodium chloride is dissolved in water?
If you are asking for the difference between the electrolysis of concentrated NaCl and aqueous NaCl, the water molecules in aqueous NaCl undergoes the Redox reactions rather than the sodium and chloride ions because the electric potential is higher. In concentrated NaCl, the chlorine atoms are oxidised instead.
What is the gas evolved at anode during electrolysis of aqueous NaCl?
Chlorine gas is evolved at the anode during the electrolysis of aqueous sodium chloride (NaCl) because chloride ions are oxidized to form chlorine gas.
Predict and explain which of the following systems are electrically conducters asolid Nacl bmolten Nacl can aqueous solution Nacl?
Solid NaCl is not an electrical conductor as the ions are held in a fixed lattice structure. Molten NaCl and aqueous solution NaCl are electrical conductors as the ions are free to move and carry charge, allowing for the conduction of electricity.
What mass of water must be added to 255.0g NaCl to make a 15.00 percent by mass aqueous solution?
To make a 15.00% by mass aqueous solution with NaCl, the mass of NaCl is 255.0g. This means that 15.00g of NaCl is present in every 100.00g of solution. To find the mass of water needed, first calculate the mass of NaCl in the final solution, then subtract this amount from the total mass of the solution (water + NaCl).
What concentration of aqueous NaCl solution freezes at -15.2ºC?
4.09 m
What chemicals can be obtained from the electrolysis of sodium chloride?
Electrolysis of a water solution: sodium hydroxide, hydrogen, chlorine..Electrolysis of molten NaCl: sodium, chlorine.
Do NaCl molecules exist in an aqueous solution of sodium chloride?
In water solutions salt is dissociated: NaCl--------------Na+ + Cl-
2 Predict and explain what systems are electrically conducting a solid NaCl b molten NaCl c An aqueous solution of NaCl?
a) In a solid state, NaCl is an insulator since the ions are held in fixed positions and cannot move to conduct electricity. b) When NaCl is melted into a liquid state, the ions are free to move and can carry an electric current, making molten NaCl an electrical conductor. c) In an aqueous solution of NaCl, the salt dissociates into ions, allowing them to move freely in the solution and carry an electric current, making it a good conductor of electricity.
What happens when aqueous solution of BaCl2 is added to aqueous solution of Na2SO3?
When an aqueous solution of BaCl₂ is added to an aqueous solution of Na₂SO₃, a double displacement reaction occurs, resulting in the formation of barium sulfite (BaSO₃), which is insoluble in water and precipitates out of the solution. The balanced chemical equation for this reaction is: BaCl₂ + Na₂SO₃ → BaSO₃ (s) + 2 NaCl. The precipitation of BaSO₃ indicates that a solid product is formed, while NaCl remains dissolved in the solution.
