# A patient with respiratory alkalosis has a blood plasma pH of 7.58. What is the [H_3O^+] of the blood plasma?

$p H = - {\log}_{10} \left[{H}_{3} {O}^{+}\right]$. Here $\left[{H}_{3} {O}^{+}\right]$ $=$ ${10}^{- 7.58} \cdot m o l \cdot {L}^{-} 1$
Here $\left[{H}_{3} {O}^{+}\right]$ $=$ ${10}^{- 7.58} \cdot m o l \cdot {L}^{-} 1 = 2.6 \times {10}^{-} 8 \cdot m o l \cdot {L}^{-} 1$.
$\left[H {O}^{-}\right]$, so I presume, is elevated with this condition. What is $\left[H {O}^{-}\right]$ here? What do you think it should be?
