Chemistry - Ionic Equilibrium Question with Solution | TestHub

A soft drink was bottled with a partial pressure of${\mathrm{CO}}_2$of 3 bar over the liquid at room temperature. The partial pressure of${\mathrm{CO}}_2$over the solution approaches a value of 30 bar when$44 \mathrm{g}$of${\mathrm{CO}}_2$is dissolved in$1 \mathrm{kg}$of water at room temperature. The approximate$\mathrm{pH}$of the soft drink is ___________$\times {10}^{-1}$.
(First dissociation constant of${\mathrm{H}}_2{\mathrm{CO}}_3=4.0\times {10}^{-7}; \log 2=0.3;$density of the soft drink$=1 \mathrm{g} {\mathrm{mL}}^{-1}$)
