A soft drink was bottled with a partial pressure of CO? of 3 bar over the liquid at room temperature. The partial pressure of CO? over the solution approaches a value of 30bar when 44 g of CO? is dissolved in 1 kg of water at room temperature. The approximate pH of the soft drink is * 10?¹ /
(First dissociation constant of H?CO? = 4.0 * 10?; log 2 = 0.3; density of the soft drink = 1 g mL?¹)
