Computer Programs for Calculating Equivalent Conductivity and Dissociation Constants A number of computer programs have been developed by the author for calcule.ting equivalent conductivibies and both classical and thermodynamic dissociation constants from experimental data. The Elliot 4120 wibh 16,384 words of store was available, and Algol was used to construct the programs. The following tnble shows the type of program available. Further information concerning these programs is available from the author. Program label
