Interpretation: The type of the solution when a solvent can hold maximum amount solute needs to be determined.
Concept introduction: For substances which are soluble, there is a maximum limit to how much solute can be dissolved in a fixed amount of solvent. For example, when sugar is added in a glass of water, at first the sugar disappears rapidly. However, upon continued addition of more sugar, at a particular point the sugar no longer dissolves but remains as a solid at the bottom of the glass.
Based on extent of solubility solutions are divided into four categories (a) saturated (b) unsaturated (c) supersaturated and (d) dilute.

Answer to Problem 2STP
Option “C” is correct.
Explanation of Solution
A saturated solution is a solution in which a solvent is incapable of dissolving more solute at a definite temperature. Since, in this case solvent holds the maximum amount solute the solution is said to be saturated.
In unsaturated solution more solute can be dissolved. A supersaturated solution is already reached its maximum limit and on further addition of solute it will not get dissolved. In a relatively small amount of solute is dissolved in large excess of solvent.
Hence, A, B, and D cannot be the option.

A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
