When a molecule with acidic protons enters into an environment with a pH value that is greater than the pK, of its functional groups, the molecule will lose the proton(s) in question. Consider the structure of the amino acid histidine in its fully protonated form. How would the amino acid appear in a slightly basic environment of pH 8, given the following structure and the pK, values of the acidic protons? Bear in mind, that when the pH of the solution is greater than the pK, of the proton, that proton will be lost. proton pK

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
