    \[pH= -\log_{10} [H ^{+}]\] So if we substitute the concentration of H+ in that equation we get the pH around 12 If a solution's pH is 1- 5 usually they are acidic solutions 7- a neutral solution 8-15 it is basic ! Since it's around 12 the solution is basic !

    There's an easier way though. Look at the H+ concentration it is very low right? If it is an acidic solution the H+ should be more than this right? If it's neutral the H+ concentration should be equal to OH- In a basic solution OH- concentration is high compared to H+ concentration. Since we can see he concentration of H+ is low it can be considered as a basic solution.

    @Rushwr As you said, \[Ph = -\log_{10}(H ^{+}) \] so here \[Ph=-\log_{10}(10)=-1 \] so the solution is heavily acidic Also, a concentration of 10 moles of H+ per liter is extremely high. So high that even some strong acids don't completely dissociate. So the solution is acidic.

    @niels5x9 U are wrong there. The given value is \[10^{-12}\] So the pH would be 12 . So it's gonna be basic ! :)

    oh well he said 10-12 so i thought he meant in the range of 10 to 12
