Question

why is the acidfied water conduct electricity

Answer 1

When you add an acid, which will dissociate into ions (or any soluble ionic compound) to water you are providing charge-carriers. 
The ions move towards the oppositely charged electrode where they gain or lose electrons to/from the electrode thus 'completing the circuit'. 
Electrons, as such, do not flow through the liquid - it is the ions that move.

Answer 2

Acidfied water conduct electricity because this water contain H+ ions which is necessary to conduct electricity.... HOPE IT HELPS.... Plzz mark as brainliast
