The electrolysis ionize the particles/ molecules present in the particles and charged the positive and negative ions. Positive ions collected on negative electrode and Negative ions collected on positive electrodes.

What event must take place to separate a compound into separate elements?
electrolysis electrolysis electrolysis electrolysis electrolysis
Is electrolysis of NaCl a chemical change or not?
Electrolysis is a chemical change.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical.
Which one is a chemical change distillation filtration oxidation and electrolysis?
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
Is electroplating physical or chemical change?
Chemical because it breaks apart the individual compounds on the molecular scale.
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
Justify why electrolysis of water is a chemical irreversible change?
A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.
When an electric currents is passed through water during the process of electrolysis?
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
Is electrolysis of water to form hydrogen and oxygen a physical or chemical change?
It is a chemical change because you are breaking the water into its elements, hydrogen and oxygen, and it is no longer water. I NEED THE NUMBER'S ^ Here They are Oxidation of ions or neutral molecules occurs at the anode, and the reduction of ions or neutral molecules occurs at the cathode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode:Fe2+ aq → Fe3+ aq + e- It is also possible to reduce ferricyanide ions to ferrocyanide ions at the cathode:Fe(CN)3- 6 + e- → Fe(CN)4- 6
How can electircity make chemicals change?
Through electrolysis, electricity can break apart molecules. A common science class experiment is the electrolysis of water.
Is it a chemical or physical change when energy in food molecules is transferred into molecules of ATP?
Chemical change.
Why is the electrolysis water classified as a chemical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
