<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.

The correct option is B.
Phenophtalein is an indicator that is usually used in acid base titration experiments. Indicators are substances that undergo distinct, observable changes when the pH of their solutions change. Indicators exhibit changing of colors depending on the pH of the solution in which they are found. They are usually weak bases and acid which are capable of partial dissociation and formation of ions when dissolved in water. There are different types of indicator and phenophtalein is one of them. Phenophtalein is colorless in acidic solution and pink in basic solutions.
