실험 절차
The disodium edetate was dissolved in the water. The cobaltous carbonate was added slowly with stirring. Gradual evolution of bubbles occurred after enough of the metal salt had been added to raise the pH to roughly 5. At that point, the insoluble material began to disappear more rapidly. After all of the bubbling had stopped, the liquid was stirred for approximately 15 minutes, and then the sodium bicarbonate was added slowly, with ample reaction time before further addition. The reaction was complete when a clear pink solution was obtained.
