Question

different between anode and cathode

Answer 1

Different between anode nd cathode is:-

Anode carrys positive electrode.

While cathode carrys negative electrode.....

Hope it's help u....

Answer 2

$\huge\mathcal{ANSWER}$

◼Electrodes allow the electric current to enter or leave the electrolytic solution.

◼The electrodes are two in number and are made up of metal or carbon.

◼Graphite (carbon) electrodes are used when the products formed during electrolysis reacts with metallic electrode.

◼The electrode are connected to a battery via a key or switch and depending on their connection to the battery are classified as ANODE or CATHODE.

$\bold{ANODE(positive \: electrode) }$

⚫ In this electrode connected to the positive terminal of the battery.

⚫The electrode hence aquires a positive charge during electrolysis and hence ions which are negatively charged anions nitrate to the an anode.

⚫The anions donate excess electrons to the anode and are oxidised to neutral atoms.

⚫The anode is the oxidising electrode by which electrons leave the electrolyte loss of electrons from an atom of ion is called oxidation, hence oxidation takes place at anode.

${Cl}^{-1} - {1e}^{-}\longrightarrow Cl(neutral \: atom)$

$\bold{CATHODE(negatively \: electrode) }$

⚫Its the electrode connected to the negatively terminal (end) of the battery.

⚫The electrode hence acquires a negative charge during electrolysis and hence ions which are positively charged cations migrate to the cathode.

⚫The cations gains excess electrons from the cathode and are reduced to neutral atoms.

⚫The cathode is the reducing electrode by which electrons enter the electrolyte. Gain of electrons by an atom or ion is called reduction, hence reduction takes place at cathode.

${Na}^{+1} + {1e}^{-}\longrightarrow Na(neutral \: atom)$
