Answer:
The correct answer would be - observing with the help of five senses.
Explanation:
To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.
Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.
Answer:
It is the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy - LOQ
The concentration is equal to three times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOD
The concentration is equal to 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOQ
It is the minimum amount of analyte that produces a signal that is significantly different from the blank - LOD
Explanation:
We define the limit of detection has the lowest amount of analyte that produces a signal that is significantly different from a blank solution ( the absence of the substance). It is calculated as three times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
The limit of quantitation (LOQ) is defined as the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy. It is measured as 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
