During electrolysis of KOH (potassium hydroxide), the potassium ions (K+) migrate towards the cathode and are reduced to form potassium metal. Hydroxide ions (OH-) migrate towards the anode and are oxidized to form oxygen gas and water. Overall, KOH is broken down into its respective elements, potassium, oxygen, and water.

How was potassium obtained?
Potassium was first isolated from potash, a substance derived from wood ashes. The compound potassium hydroxide was then isolated and used to produce metallic potassium through the process of electrolysis. Today, potassium is primarily obtained commercially through the electrolysis of potassium chloride.
How do you prepare methanolic KOH?
The formula "K" refers to potassium hydroxide. When dissolved in methanol (OH), it becomes KOH, or methanolic potassium hydroxide. This is an extremely volatile liquid, so the utmost care must be taken in preparation.
Why are substances like platinum and palladium often used for carrying out electrolysis of aqueous solutions?
that is because platinum and palladium are inert elements and they wont react with the substance deposited on the electrode.. unlike if we use carbon electrodes, carbon will react with oygen deposited on it and escape out as CO2 gas
How do you make ethanolic KOH?
To prepare ethanolic KOH, you can dissolve potassium hydroxide (KOH) pellets in ethanol (ethyl alcohol). This process should be done slowly and carefully as it generates heat. It is important to wear appropriate safety gear, work in a fume hood, and follow proper lab protocols when handling these chemicals due to their caustic nature.
What is the neutralization process and give an example of the reaction using hydrochloric acid and potassium hydroxide?
Neutralization process is a type of chemical process in which a base(usually an alkali which is a soluble base) reacts with an acid to produce salt and water only. Example: a reaction between KOH and HCL. HCL + KOH ----> KCL + H20.

What happens when you combine KOH and NaCl?
Nothing happens. It is still NaCl and KOH.

Who found the Koh-i-noor diamond?
The Koh-i-noor was found sometime during about the 13th century A.D., and the person who picked it up has a name that has been lost to history.
How do you pronounce kokiriko?
Koh-Kee-Ree-Koh

What is the formula for the ionic compound from potassium hydroxide?
The formula for the ionic compound formed from potassium hydroxide is KOH. This is because potassium (K) has a +1 charge and hydroxide (OH) has a -1 charge, so they combine in a 1:1 ratio to form a neutral compound.
What happens when potassium hydroxide reacts with nitric acid?
When potassium hydroxide (KOH) reacts with nitric acid (HNO3), potassium nitrate (KNO3) and water (H2O) are formed. The overall reaction can be represented as: KOH + HNO3 → KNO3 + H2O
What mass of KOH is needed to make 400mL of 725 M KOH?
I assume you mean 7.25 M KOH, but the process is the same anyway.Molarity = moles of solute/Liters of solution ( 400 ml = 0.4 Liters )7.25 M KOH = X moles KOH/0.4 Liters= 2.9 moles KOH (56.108 grams/1 mole KOH)= 163 grams potassium hydroxide needed===============================
