What is the [H3O+] in a solution with [OH-] = 1.0 x 10-12 M?

1.0 x 10-2 M

1.0 x 10-8M

1.0 x 10-12M

1.0 x 102 M

The concentration of hydronium ions in the solution is M.

Explanation:

Concentration of hydroxide ions concentration =

The pOH if the solution is given by :

pOH = 12

The relation between pH and OH is given by : pH + pOH = 14

pH = 14 - pOH

pH =14 - 12 = 2

The pH of the solution isgiven by :

The concentration of hydronium ions in the solution is M.

i believe that it is a exoplanet

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.
