What is kclo4 a weak acid, weak base, acidic salt, basic salt, or a neutral salt

A neutral salt

Explanation:

is formed when KOH ( Potassium hydroxide ) and ( generally know as Perchloric Acid ) which is strong acid react with each other.

The ions of is in which  both have not any tendency to donate or accepet any electrons so  is neutral salt

where are the choice options?

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.
