Answer 1

A person unable to judge the lower meniscus of burette at the end point during the titration comes under personal error

Explanation:

1.Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique(personal error).

2.Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette.

3.titration, process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion.

Answer 2

Answer:

A person unable to judge the lower meniscus of the burette at the endpoint during the titration comes under personal error.

Explanation:

• Personal error refers to faults produced as a result of the observer's mistake, such as carelessness in taking notes, and so on.
• Personal errors can take many forms, including inaccurate gauge readings, miscalculations while diluting components or doing other computations, spills while handling chemicals during transfer, and following the wrong experiment directions.
• It is constantly present and can be reduced with the right training and experience, but it cannot be completely eliminated.
