Stability constants K-12(0) for electrically neutral calcium complexes in a
queous solution were found to have a relationship with solubility products
L-0 of corresponding salts described by the equation log K-12(0) = 1.59 - 0
.18 log L-0 with a correlation coefficient of 0.99. The stability constant
at 25 degrees C for the CaCl20 complex was estimated at 0.34.
