Question 6
Which of the following statement is INCORRECT?
Gravimetry and titrimetry are classical method of analysis because measuring the
mass and volume is the fundamental of all analytical measurements, thus those
two are the oldest analytical technique.
O Analytical Chemistry involves the application of techniques and methods to obtain
and assess qualitative, quantitative, and structural information on the nature of
matter.
O Quantitative reveals the identity of the elements and compounds in a sample
while qualitative analysis analysis indicates the amount of constituent present in a
sample.
Analytical Chemistry deals with methods for determining the chemical
composition of samples of matter. It is a measurement science consisting of a set
of powerful ideas and methods that are useful in all fields of science and medicine.

Question 23
Which of the following is INCORRECT?
O Calibration determines the relationship between the analytical response and the
concentration of analyte.
O The range in the calibration curve between the relationship of analytical response
and concentration of analyte is the concentration interval over which linearity,
accuracy, and precision are all acceptable.
O The detection limit (DL) or also known as the limit of detection (LOD) is the
smallest concentration that can be reported with a certain level of confidence.
O In external standard method, the signal (SA) is inversely proportional to the
concentration of analyte (CA). Therefore, the formula is SA=KACA where the k is
method's sensitivity.
