Question
Chapter 1.2, Problem 1RQ
Interpretation Introduction
Interpretation: The difference between a qualitative observation and a quantitative observation needs to be explained.
Concept Introduction: Observations are essential in the subject chemistry. Chemists use observations to collect as well as record the data. Through observations, researchers develop and test hypotheses & theories.
Expert Solution & Answer
Answer to Problem 1RQ
Qualitative observation is generally conducted on a small data
Explanation of Solution
The difference between a qualitative observation and a quantitative observationis mentioned below:
| Qualitative observation | Quantitative observation |
| Qualitative observations use a person’s sense to observe the result. | Quantitative observations are observed with instruments (ruler, beakers, etc.) |
| Qualitative observations are variable. | Quantitative observations are invariable. |
| Qualitative observations are not accurate. | Quantitative observations are accurate. |
| Qualitative observations are not measurable. | Quantitative observations are measurable. |
| Qualitative observations cannot be noted in expressions of numbers. | Quantitative observations can be noted in expressions of numbers. |
For example: Freezing point of  is more polar than its boiling point. | For example: The freezing point of  is  The boiling point of  is  |
