Detailed explanation-1: -A calibration is the process of experimentally determining the value of kA by measuring the signal for one or more standard samples, each of which contains a known concentration of analyte. With a single standard we can calculate the value of kA using Equation 3.3.

Detailed explanation-2: -The substance that we want to know the amount of in a sample is called the analyte. In order to determine the concentration of a particular analyte in a sample we must perform a procedure called “concentration calibration”.

Detailed explanation-3: -In analytical chemistry, calibration is defined as the process of assessment and refinement of the accuracy and precision of a method, and particularly the associated measuring equipment (i.e., an instrument), employed for the quantitative determination of a sought-after analyte [2].

Detailed explanation-4: -Calibration is the process of determining the response of an instrument to a particular analyte, or the relationship between the signal and the amount of analyte in a sample. Q1. As a group, devise a way in which you could determine how the signal from an unknown amount of analyte corresponds to its concentration.

Detailed explanation-5: -To standardize an analytical method we use standards that contain known amounts of analyte. The accuracy of a standardization, therefore, depends on the quality of the reagents and the glassware we use to prepare these standards.
