Freezing point and boiling point of the solutions to be calculated. 5g NaCl into 25g water Concept introduction: Freezing point: Freezing point is defined as the temperature at which liquid into solid. Boiling point: Boiling point is temperature at which the liquid into gas. Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent. Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). 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).
