Ions carbonate ph
WebSolubility. Carbonate ion can be precipitated from solution as white barium or calcium salts that have low solubilities: Although many carbonate salts are insoluble, those of Na +, K +, and NH 4 + are quite soluble. All bicarbonate ( HCO 3 −) salts are soluble. Because of this, even insoluble carbonate salts dissolve in acid. WebThe pH values can be calculated based on pKa values. The pH of a 0.02 mol solution is calculated to be 11.3. In water CO2 is the predominant species at a pH lower than 6.33, HCO3- (hydrogen carbonate ion) at a pH in the range of 6.35-10.33, and CO3^2- (carbonate ion) at a pH higher than 10.33.
