What is the [OH^-][OH−] in a solution that has a [H_3O]=1.0*10^-6[H3O]=1.0⋅10−6 MM?
1 Answer
The solution has a
Explanation:
The answer can be obtained one of two ways:
color(red)("Use the auto-ionization constant of water equation, Kw:"Use the auto-ionization constant of water equation, Kw:

All you would have to do is rearrange the equation to solve for[OH^(-)][OH−] by dividing both sides of the equation by[H_3O^(+)]:[H3O+]:
Plug in the known concentration of
2.
Determine the pH of the solution by taking the negative logarithm
(-log) of the concentration of
Then obtain the pOH using the equation:
Finally, you take the anti log (inverse of the natural logarithm),
