# Problem: The pOH of a sample of baking soda dissolved in water is 5.74 at 25ºC. Calculate the pH, [H +], and [OH -] for this sample. Is the solution acidic or basic?

###### FREE Expert Solution

The OH- concentration can be calculated from pOH using the following equation:

$\overline{)\left[{\mathbf{OH}}^{\mathbf{-}}\right]{\mathbf{=}}{{\mathbf{10}}}^{\mathbf{-}\mathbf{pOH}}}$

$\left[{\mathbf{OH}}^{\mathbf{-}}\right]{\mathbf{=}}{{\mathbf{10}}}^{\mathbf{-}\mathbf{5}\mathbf{.}\mathbf{74}}$
