Why does potassium metal not collect at the cathode when aqueous solution of potassium hydrochloride is electrolyzed?

The reduction of hydrogen from water to produce hydrogen gas occurs at a lower electrical potential difference than the reduction of potassium ions to potassium metal. In even a concentrated aqueous solution, the supply of water present is usually adequate for this reaction to consume all the available electric current. Also, any small amount of potassium metal that might form would react very rapidly with water to release hydrogen gas.

Why does potassium chloride conduct electricity in aqueous solution?
its depends in the amount of potassium chloride.
Why does an aqueous solution of iodine not react with potassium chloride?
because it dosent
Hydrochloric acid and potassium hydroxide react together in an aqueous solution. Which compound is a product of the reaction?
potassium chloride (KCl)
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.
Why does potassium chloride conduct electricity?
Potassium chloride is an ionic solid, the ionic solids can conduct the electricity if they are in molten state or in aqueous solution.
What is aqueous potassium nitrate?
Just potassium nitrate in water. Aqueous stands for anything with water, so if you take dry potassium nitrate and add some water to it until it dissolves, you have made an aqueous solution of potassium nitrate.
Why does potassium chloride conduct electricity in aqueous solution?
its depends in the amount of potassium chloride.
Why is an aqueous solution of potassium nitrate considered to be homogeneous?
Yes
What is the composition of fehling's solution?
Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate, Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
Why does an aqueous solution of iodine not react with potassium chloride?

A dilute aqueous potassium nitrate solution is best classified as a?
homogeneous mixture
When aqueous solutions of potassium fluoride and nitric acid are mixed an aqueous solution of potassium nitrate and hydrofluoric acid results Wirte the net ionic equation for the reaction?
When aqueous solutions of potassiumfluoride and hydrobromic acid are mixed, an aqueous solution of potassiumbromide and hydrofluoric acidresults. Write the net ionic equation for the reaction.
How does ferric chloride reacts with potassium iodide solution?
In aqueous solution they would not react. They would form a solution of ferric ions, chloride ions, potassium ions, and iodide ions.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
