Hint: we are asked to seek out the reagent used for quantitative analysis of $Co^{2+} $+ ion. So , first we'll discuss the quantitative analysis then we will discuss the reagent used for quantitative analysis of $Co^{2+} $ ion.
Complete step by step answer:
Quantitative analysis may be a class of techniques to determine the mass or concentration of a substance by measuring a change in mass within the laboratory. The chemical we try to quantify is named the analyte.
The reagent utilized in the quantitative analysis of $Co^{2+} $ is $\alpha−nitro−\beta−naphthol$ . quantitative chemical analysis may be a method of quantitative analysis in a chemistry lab during which the constituent sought is converted into a substance (of known composition) which will be differentiated from the sample and weighed.
So, the correct answer is Option B.
Additional Information:
The principle behind quantitative analysis in chemistry is that the mass of an ion during a pure compound is often determined then want to know the mass percent of an equivalent ion during a known quantity of an impure compound.
Gravimetric examination may be a method through which the measure of the particle being determined and may be resolved through the estimation of mass
Note: The identification of any element or compound is often done by both chemical analysis or quantitative chemical analysis . Gravimetry may be a quantitative chemical analysis and is predicated on the mass of a given solid while chemical analysis is predicated on volume analysis. While a volumetric analysis is different from quantitative analysis . A volumetric system doses material consistent with the space it occupies i.e. its volume; a gravimetric system determines the quantity of fabric to be dosed by weight.
