Explanation:

Ions are the species that contain either a positive or negative charge.

For example, PO^{3-}_{4}, Al^{3+}, Hg^{2+}_{2}, HCO^{3-} are all ions.

Whereas when two or more different atoms are bonded together then the product formed is known as a compound.

For example, Na_{2}CO_{3} is a compound.

On the other hand, species that do not contain any charge are known as neutral species.

For example, fe, Zn, Cu are all neutral atoms.

Thus, we can conclude that items which represent the ions are as follows.

PO^{3-}_{4}, HCO^{3-}, Al^{3+}, and Hg^{2+}_{2}

<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.
