pisgahchemist say: Basic solution....

All aqueous solutions contain both hydrogen ions, H+(aq), and hydroxide ions, OH-(aq). They come from the auto-ionization of water and from either acids or bases.
HOH(l) <==> H+(aq) + OH-(aq) ........... Kw = 1.00x10^-14 ........... at about 25C

Kw = [H+][OH-] = 1.00x10^-14
For a neutral solution [H+] = [OH-] = 1.00x10^-7M

A solution is defined as basic when the hydroxide ion concentration is greater than the hydrogen ion concentration as is the case in your question.

Kw = [H+][OH-]
[H+] = 1.00x10^-14 / 4.6x10^-6 = 2.2x10^-9M
[OH-] > [H+] ..... therefore, the solution is basic
