Systemaic Treatment of Equilibrium In solving chemical equilibrium, we often make approximation to simplify the mathematical solution. For instance, the approximation of negligible dissociation of weak acids. Here, we will explore the use of R to solve equilibrium without approximations. We find the equation to solve through aplication of a syste...

Introduction In a previous article 1 and in a monograph2, we have discussed a methodological problem in comparing performance of a PLTL group of students with a non-PLTL group. Often, average test scores between the two groups are compared. On first glance, this appears to be a reasonable and straightforward procedure. However, this approach is v...

The R Programming Language Every programming language has similar elements. We need to input data, identify variables, perform calculations, create functions, control program flow, and output data and graphics. The R language is attractive in that it has it has a full online development environment -RStudio Cloud- and built in functions for regre...

R for Analytical Chemistry
1 Preface This book originated from an effort to integrate programming into the teaching of Analytial Chemistry (or Quantitative Chemical Analysis, as it is sometimes called). In choosing a language, I found in R the following desireable qualities for teaching: A comprehensive online platform in R Studio Cloud. Easy to get up & running. Quality ...

Acid/Base Binding Curve Adapt to titration data, framed as fraction binding as determined from the endpoint, vs pH (which is actually equilibrium ligand H) We can transform titration data to a binding curve representation. For the equilibrium: \(HA \rightleftharpoons H^+ + A^-\) \(K_a = \frac{[H^+][A^-]}{[HA]}\) we are measuring H+ and for a weak...
