19.  Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–11 mol/L. Is this solution acidic, basic, or neutral? Show your work.(3 points)

[H+] and [OH-] = 1 x 10^-14

Since we know that [OH-] is 1 x 10^-11 we would divide...

$\Huge{\frac {[OH-] [ H+] }{[OH-]}}$

563blackghost · Answer

So...

$\Huge{\frac{1 \times 10^{-14}}{1 \times 10^{-11}}=[H+]}$

563blackghost · Answer

If [H+] is greater than [OH-] then it would be acidic if it is not then it would not be acidic...

Did you understand as to what I typed?

1 x 10^-3 = 3 < 7
pH=3 <7 solution is acidic.
 I am wondering if this is right? @563blackghost

563blackghost · Answer

Correct :) The [H+] is 1 x 10^-3 as well as acidic ^^
