What is the concentration of a strong base solution (of an alkali metal) that has a pH of 11.39?

Explanation:

Hello there!

In this case, since a strong base produce OH ions in solution, it possible to first compute the pOH as shown below:

Thus, via the definition of the pOH we can compute the concentration of the strong base as follows:

Thus, solving for the concentration we obtain:

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.
