Question

What substance can be added to distilled water in a small amount to make it a good conductor of electricity and why

Answer 1

sulphuric acid i.e. H2SO4 can be added to make it a good conductor of electricity because it releases H+ ions in aqueous solution hence it conducts electricity

Answer 2

A small amount of salt that is (NaCl) can be added to distilled water to make it conductive, this is because salt is made up of ionic bond between Na+ and Cl- ions so when they get dissolved in water or are in an aqueous solution the ions are tend to move freely and thus they makes the water conductive.
