Answer 1

Answer:

instrumental method is not calibrated

Answer 2

The right response to the given question is option a: Instrumental error.

• A pipette is a laboratory tool used in analytical laboratories to extract specific reagents in minute amounts, and it is sucked with the mouth.
• It's calibrated with microscopic indications so you can get the right amount of any reagent for your analysis.
• Calibration of an instrument is the process of making these markings with the use of a standard or reference.
• When this caliberation is not done properly, or if the markings on the instrument are not visible clearly or are not distinctly indicated, the measurements are erroneous.
• An instrumental error occurs when inaccurate data are acquired as a result of flaws in instrument markings or calibration.
• Personal error is attributable to a flaw in any stage of the complete analytical technique, whereas method error is related to a flaw in any phase of the entire analytical procedure.
• Hence the correct answer is an instrumental error.
