because chloride ions being negatively charged have got a tendency to get attracted to positive ions( follows from coloumbs law) and since positive electrode contains positive ions so chloride free ions in solution gets attracted to the positive electrode....
when current is passes, electrodes have charges and they attract oppositely charged ions.
Then the anode (positive) will attract the anions (negative) and the cathode (negative) will attract the cations (positive).
like charged ions repel, while oppositely charged ions attract.
Sodium's electron configuration means that there is just one electron in its outer shell, when becoming an Ion it is easier for it to "donate" this electron to the element it is forming a compound with. This means that the Sodium ion is no longer electrically balanced (it has lost a negatively charged electron) and becomes overall positively charged. Being positively charged it will of cause be attracted to the NEGATIVE electrode as oposite charges attract and similar charges repel.
They form an ionic compound.
Ammonium Perchlorlate - NH4ClO4 The negative perchlorate ion (NH4+) is ionically attracted to the positive ammonium ion (ClO4-).
Since water is a slightly polar molecule (the hydrogen end being slightly positive and the oxygen ends being slightly negative) the positively charged sodium ion (Na+) will be attracted to the oxygen end of the water molecule.
forms a covalent bond APEX:They form an ionic compound.
glass electrode, antimony electrode, the hydrogen electrode
A glass electrode is made of a doped glass membrane and is an electrode which is ion-selective.
why is an iron ion attracted to a sulfide ion but not to a zinc ion

Negative electrode Cathode One on the right
The glass electrode is made in such a way that it is only sensitive to the specific ion.
positive ions
A positive ion is called a cation. It forms when an atom loses one or more electrons, resulting in a net positive charge. Cations are attracted to anions, which are negative ions, due to their opposite charges.
Lithium ion batteries use lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode). Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge. Ms.Helen Ren
