Write a mechanism (using curved-arrow notation) for the deprotonation of tannins in base. use ar-oh as a generic form of a tannin and use sodium carbonate (na2co3) as the base. balance the chemical equation. comment on the aqueous solubilities of each species (assume that the tannin is insoluble in water initially)

After deprotonation of tannin, tannin (Ar-OH) is converted to salt which is soluble in water and is converted to which is also soluble in water

Explanation:

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.
