Question

A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two colorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?

Answer 1

Answer:

Given that a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading.

Though consistent, the first colorimeter has a zero error of -5.

Hence whenever first calorimeter is used this adjustment to be made i.e. actual reading +5 should be made to get correct reading

But second can be used as such taking the reading as correct.
