Calculate the pOH of a solution with a proton concentration of 5.0 x 10-11M

=

Also, is it Acidic, Basic, or Neutral

3.7; basic

Explanation:

 [H⁺] = 5.0 × 10⁻¹¹ mol·L⁻¹

  pH = -log[H⁺] = -log(5.0 × 10⁻¹¹) = 10.3

pOH = 14.00 - pH =14.00 - 10.3 = 3.7

The solution is basic, because [H⁺] < 7.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
