Glenn T. Hefter Solubility, Solubility data series A known volume of water, typically 50 mL, was placed in a stoppered Babcock tube having a neck graduated from 0 to 1.6 mL in steps of 0.02 mL. An excess of solute was added and the mixture allowed to come to equilibrium in a constant temperature bath then centrifuged. The amount of solute dissolved was etermined by subtracting the undissolved solute measured directly in the neck of the tube from the total added.
