If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
potassium chloride
Why is hydrogen collected at cathode instead of sodium during the electrolysis of sodium chloride?
When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
Is Hydroxide and element?
Hydroxide is not an element. Instead, it is a polyatomic anion that contains the two elements hydrogen and oxygen.
Why is ammonium chloride used as a paste instead of a dry solid in a dry cell?
ammonium chloride is moist
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
What is electrolysis of aqueous sodium chloride?
Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
potassium chloride
Can sodium chloride be used to make soap instead of lye?
No, because sodium chloride isn't alkaline; you could use sodium hydroxide instead of potassium hydroxide (lye) but sodium chloride wouldn't work very well.
Why do you use molten NaCl in electrolysis instead of an aqueous solution of NaCl?
Molten salt electrolysis is used to obtain sodium and chlorine. Electrolysis of the water solution is used to obtain sodium hydroxide and hydrogen.

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.
Why electrolysis does not happen in solid sodium chloride?
when an aqueous solution is used, hydrogen gas is evolved at cathode, instead of depositing sodium metal.
Is Hydroxide and element?
Hydroxide is not an element. Instead, it is a polyatomic anion that contains the two elements hydrogen and oxygen.
Why is magnesium hydroxide used as an antacid instead of sodium hydroxide?
Sodium Hydroxide is way too basic (very high pH) and would cause internal damage.
What are the catalysts used in friedel-crafts reactions instead of stannic chloride?
aluminum chloride
What reaction takes place between ammonium chloride and sodium hydroxide?
It would be predicted that it would smell like ammonia, but when performing the actual test myself I found no odor change. I would probably predict a possible pH change.

What is chloride anomaly?
In reference to Electrolysis, the chloride anomaly is the tendency for chloride ions to react with the water molecules in an electrolytic cell which defies the common trend of oxidation and reducing agents to react with the most similar electrode potential. Specific Example: NaCl and Water with graphite electrodes. Predicted Reactions: H2O + e- => 1/2H2 + OH- 1/2O2 + 2H+ + 2e- => H20 Chloride anomaly means this happens instead: H2O + e- => 1/2H2 + OH- Cl- => 1/2 Cl2 + e-
