Its use is somewhat controversial since it can leach from glazes into food and drink. Can a general surgeon do a cardiothoracic surgery? They react with each other in the molar ratio of 2:1. display: inline-block; These species are not CO , so they do appear in the Ksp expression. Substituting the desired oxalate concentration into the equilibrium constant expression, \[\begin{align}8.7\times10^{-6}=\dfrac{[\mathrm{H^+}]^2[\mathrm{ox^{2-}}]}{[\mathrm{HO_2CCO_2H}]} &= \dfrac{[\mathrm{H^+}]^2(2.32\times10^{-7})}{1.0} \\ [\mathrm{H^+}] &=\textrm{6.1 M}\end{align} \nonumber\]. text-align: center; This cookie is set by GDPR Cookie Consent plugin.
