It is used to predict the solubility of unknown solutions c) A calibration curve is used to determine unknown quantities of sugar in different beverages. Known quantities are not needed to develop a calibration curve.

Solution

Calibration Curve: It is a method to determine the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

(a) Given Temperature: So, according to the definition, option(a) is the wrong

(b) Given Saturation level of the solution: So, according to the definition, option (b) is the wrong

(c) Given Unknown Quantities of sugar in different beverages.

Substance: Sugar, its quantity determines the concentration, in an unknown sample. But the sample is the beverage which is known.So, according to the definition, option (c) is the wrong

(d) Correlates Measured Data to Known Data, which is correct according to the definition. Right answer option (d)
