1) If the [H+] in a solution is 1.0 × 10−3 M, is the solution acidic, basic, or neutral? What is the [OH−] of this solution? 2)If the [OH-] in a solution is 1.0 × 10−9 M, is the solution acidic, basic, or neutral? What is the [H+] of this solution? 3) Define the following in terms of ions concentrations: a- Acidic solution b- Neutral solution c- Basic solution 4)How are [H+] and [OH−] related in an aqueous solution?

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
