Question

why anode is called oxidising electrode , while it loses electrons to anion.
I am confused please help.

Answer 1

✸✸GOOD EVENING FRIEND✸✸

➦HERE IS UR ANSWER✌✌

➠➠In Anode always oxidation occur

➠➠In Cathode always reduction occur.

➠➠Oxidation means losing of electrons

➠➠Reduction means gaining of electrons.

I HOPE FROM THE ABOVE POINTS ALL UR DOUBTS ARE CLEARED.

✿NAZ✿

IF ANY MORE DOUBTS PLZZ ASK IN COMMENTZZ❤❤

THANK U

Electrolysis come from two words: ‘electro’, which you might have guessed, means ‘electricity’, and ‘lysis’, which comes from Greek and means ‘breaking’. You can thus infer that electrolysis means breaking things up with electricity and in this case, molecules to form charged particles called ions. Note that electrolysis doesn’t chiefly include breaking only; it can also join and make!

First, we need to understand that electrolysis is not far away from other processes we intuitively understand. For example, we all know how wood burns in air to give off heat. In this case, the thermal energy is used to drive the reaction forward to burn ‘wood’ to make ‘carbon dioxide’, ‘water’ and other products. A particular case here is that while it takes energy to drive the reaction forward, it releases more than it uses up energy (you will experience this excess energy as heat).

Now, electricity is a kind of an energy supply as well. Just like burning wood, we use electricity to drive forward a chemical reaction. We can use to separate molecules or release locked ones. An example of this would be using electrolysis to make hydrogen gas from water.

Ions

Thus, the first thing to understand in electrolysis is what makes it up: ions. What are ions? If you look at a sodium metal atom, you will notice it has 11 protons and 11 electrons (plus some number of neutrons as it can vary; however, the number of protons and electrons never vary in a neutral atom). Furthermore, looking at it’s atomic structure will give you an idea that there is one lone electron circling the outermost circle. Electrons are negatively charged while protons are positively charged, thus these two charges will balance each other.
