Description Usage Arguments Value Author(s) Examples
This function calculates and plots the titration curve for a monoprotic strong acid analyte using a monoprotic strong base as the titrant. The calculation uses a single master equation that finds the volume of titrant needed to achieve a fixed pH, as outlined in R. de Levie's Principles of Quantitative Chemical Analysis (McGraw-Hill, 1997).
1 2 |
conc.acid |
Molar concentration of the strong acid analyte; defaults to 0.10 M. |
conc.base |
Molar concentration of the strong base titrant; defaults to 0.10 M. |
pkw |
The pKw (or pKs) value for the solvent; defaults to water as a solvent with a pKw of 14. |
vol.acid |
Initial volume, in mL, of the solution that contains the strong acid analyte; defaults to 50.00 mL. |
plot |
Logical; if TRUE, plots the titration curve. |
eqpt |
Logical; if TRUE, draws a vertical line at the titration curve's equivalence point. |
overlay |
Logical; if TRUE, adds the current titration curve to the existing titration curve. |

Additional arguments to pass to |
A two-column data frame that contains the volume of titrant in the first column and the solution's pH in the second column. Also produces a plot of the titration curve with options to display the equivalence point and to overlay titration curves.
