1. They can be used to determine the concentration of an unknown sample - True. Calibration curves are often used in analytical chemistry to determine the concentration of an unknown sample by comparing its response to a series of standard samples with known concentrations.

2. They allow us to relate an instrument's response to an analyte - True. Calibration curves provide a relationship between the instrument's response (like absorbance in spectrophotometry) and the concentration of the analyte.

3. Calibration curves are only applicable to UV-Vis spectrophotometry - False. Calibration curves are used in many analytical techniques, not just UV-Vis spectrophotometry. They can be used in any method where the response of the instrument can be directly related to the concentration of the analyte.

4. They can be used to determine the identity of an unknown sample - False. Calibration curves can determine the concentration of an analyte in a sample, but they cannot identify the analyte. Other techniques are needed for identification.

5. A calibration curve can be generated using a single standard sample - False. A calibration curve requires multiple standard samples of known concentrations to establish a relationship between the instrument's response and the analyte concentration.

6. A calibration curve must be prepared from several standard solutions - True. As mentioned above, multiple standard samples are needed to create a calibration curve. This allows for a range of responses to be recorded, which can then be used to determine the concentration of an unknown sample.
