It has been determined that the rate of СО2, Са2+ and Н+ concentration change in the "CaCl2 + NaHCO3 + HOH + CO2" system previously saturated with carbon dioxide as a result of its air blowing out has a pulsation character. Oscillation amplitude is greater than measurement errors. Furrier’s analysis of these processes has been made and characteristic oscillation periods that are not connected with temperature pulsation have been determined. Specified periods are compared to characteristic time of inner transformations in the system. Some of these periods are close to the known СО2 hydrolysis time and СаНСО3+ complex dissociation.
