Answer:

Hg∧2+ has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.

Hg2 ^2+ has a positive standard entropy because the ionic size of Hg^2+ is smaller than Hg2 ^2+, so therefore the Hg^2+ is highly solvated and that means that it is in highly ordered state. Hg2 ^2+ is not highly solvated so it will have a positive entropy

Explanation:

The values of standard entropy of aqueous ions has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.

For which electrode could you use an inactive material

kow [346]

Mercury and carbon two electrodes can't be used with an inactive or inert material.

<h3>What is an electrode?</h3>

The electrode is the element which is used to complete the electric circuit in welding. Some time electrode is connected with the positive terminal and sometimes with a negative terminal, it depends on the requirement of the welding process.

Inert electrode is an electrode that serves only as a source or sink for electrons without playing a chemical role in the electrode reaction. Precious metals, mercury, and carbon are typically used as inert electrodes.

Therefore, neither of the two electrodes can be used with an inactive or inert material.

<h3>What is spectrometric method?</h3>

A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.

There are two main techniques used among the various forms of spectrophotometry:
ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.

Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.
