Question

Why does an aqueous solution of acid conduct electricity?


b.how does the concentration of hydrogen ions (h3o+) changes when the solution of an acid is diluted with water?


c.which has higher ph. a concentrated or dil solution of hcl?


d.what would you observe on adding hcl acid to :1)sodium bicarbonate placed in a test tube. 2)zinc metal in a test tube?

Answer 1

Aqueous solution of acid conduct electricity because it has a higher concentration of hydronium ion to carry electricity.
b. when acid is diluted the concentration of hydronium ion increases as hydrogen ion present in acid react with water to form more hydronium ion.

d.when HCl is added to sodium bicarbonate a gas is evolved which turn the lime water milky.
when HCl is added to zinc a gas is evolved which burns with pop sound.

Answer 2

Heya mate
The answer of ur question is

The aqueous solution of an acid conduct electricity because the acid solution have ions and the movement of these ions in solution helps for flow of electricity current through the solution.And the ions are H+ ions.

hope it helps
