Question

We add HCl to water so that it will become a good conductor of electricity when ions of HCl will be splited but can H+ ion remain freely?

Answer 1

HCl, or hydrochloric acid, dissolves freely in water, with its ionic bonds releasing to create H+ and Cl- ions in solution. This happens because Hydrogen is able to release its electron, and Chlorine has a high affinity for electrons, so when the two of them join, the bond they create actually involves a tranfer of electrons from H to Cl; when this bond is broken the electrons stay with the Cl, creating ions.  The presence of these ions allows electricity to flow through the solution, thus making it a conductor.
