Three manufacturers are producing carbonated bottled water. One company introduces carbonate by bubbling carbon dioxide into water until CT=10-3 M (equivalent to adding "H2CO3*" until CT = 1 x 10-3 M), a second adds sodium bicarbonate (NaHCO3) until CT = 10-3 M, and a third adds sodium carbonate until CT=10-3 M. ("CT" is the total concentration of all carbonate species, i.e., [H2CO3*], [HCO3-], and [CO32-].) Estimate the pH of the bottled water from each of the three manufacturers.
