Question

Explain the following statement: "The validity of a chemical analysis ultimately depends on measuring the response of the analytical procedure to known standards."

Short answer

The given statement should be accepted.

Step-by-step solution

Analytical procedure response

When an analytical procedure responds correctly to a known standard, then it is accepted as a valid analytical procedure for chemical analysis.

Explanation of the given statement

The response of an analytical procedure while measuring an analyte of a known quantity has to be done first before the use of the procedure to measure an unknown.

Hence, we have to measure the pure form of an analyte to use it as a calibration standard.
