Claim 9:
10. A carbonate enhancing composition consisting of:
a solubility enhancing aqueous composition consisting of an anionic component consisting of sulfate ions, alone or in combination with bisulfate ions, having a concentration from about 8.00 moles per liter to about 13.00 moles per liter of the solubility enhancing aqueous composition volume; a cationic component consisting of ammonium ions having a concentration from about 1.45 moles per liter to about 2.01 moles per liter of the solubility enhancing aqueous composition volume; and hydrogen ions in a concentration from about 17.38 mols per liter to about 21.68 moles per liter of the solubility enhancing aqueous composition volume;
sodium hydroxide solution having a concentration of about 5% to about 7.5% volume/volume of the total aqueous phase volume of the carbonate enhancing composition;
a sulfate selected from the group consisting of copper sulfate, silver sulfate and combinations thereof having a concentration from about 20 percent to about 26 percent mass/volume of the total aqueous phase volume of the carbonate enhancing composition;
at least one surfactant selected from the group consisting of non-ionic surfactants and anionic surfactants having a concentration from about 0.05 percent to about 0.15 percent volume/volume of the total aqueous phase volume of the carbonate enhancing composition; and
at least one base or at least one acid to adjust the final pH of the carbonate enhancing composition in the range from about pH 2.5 to about pH 3.5.
