Cathode (reduction): 2 H2O(l) + 2e− → H2(g) + 2 OH-(aq)Anode (oxidation): 4 OH-(aq) → O2(g) + 2 H2O(l) + 4 e−Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g)

What causes bubbles to form when electricity is passed through acidic water?
The bubbles are hydrogen and oxygen, formed from the electrolysis of the water by the electric current. Oxygen gas accumulates at the anode. Hydrogen gas accumulates at the cathode.
Why on electrolysis of zinc nitrate zinc is formed on cathode?
The cathode is so named because it provides available free electrons, to which any cation such as zinc is attracted. When a zinc ion accepts an electron, it becomes a zinc atom and usually remains attached to the cathode, which therefore becomes plated with zinc. Since metallic zinc is itself electrically conductive, the process can continue until the supply of zinc cations from the solution is exhausted, so long as sufficient electrical energy is supplied.
What are the 2 gaseous elements formed when electric current passes through acidified water?
Hydrogen & Oxygen ... xx receive
What type of electric charge does an aluminum electrolysis reaction need?
Aluminium metal is formed at the carbon anode (negative).
After three half lives what fraction of the daughter product has formed?
91.16% of the daughter product has formed after 3.5 half lives.
What is formed at the anode and the cathode during the electrolysis of sodium iodide?
If a solution of NaI is electrolyzed, iodine is formed at the anode and hydrogen gas at the cathode. In the instance if it is the molten liquid of NaI, it would emit sodium from the sodium at the cathode and iodine at the anode.
What would be formed at the cathode and the anode during the electrolysis of sodium hydroxide solution?
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
What is product formed after electrolysis at the positive and negative electrodes respectively?
The answer depends on what the electrolyte is!
Preparation of C5H11OH with grignard reagent?
When C4H9-Mg-Cl reacts with formaldehyde and product is treated with acidified water pentyl alcohol (1-pentanol) is formed.
What valuable product are formed from the electrolysis of brine?
Chlorine gas and sodium hydroxide, which is why it's called the chlor-alkali process.
What is the product of potassium permanganate and acetaldehyde?

What causes bubbles to form when electricity is passed through acidic water?
The bubbles are hydrogen and oxygen, formed from the electrolysis of the water by the electric current. Oxygen gas accumulates at the anode. Hydrogen gas accumulates at the cathode.
What are the products formed when an electric current is passed into acidified water?
Hydrogen and oxygen

How is potassium formed?
It is so reactive it has to be made by electrolysis of molten KCl
