Question
Chapter 10, Problem 10.3QAP
Interpretation Introduction
Interpretation:
The three emission analysis sources needs to be compared to explain the supremacy of ion lines in one and of atomic lines in the other two.
Concept introduction:
The three emission sources behave differently due to their temperature ranges and also due to the ionization of argon gas.

The content of sodium in a cooking salt substitute for a low-sodium diet can be determined by atomic emission spectroscopy using the addition standard calibration method. 10.07 g of sample are weighted and solved in 10 mL 1M HCI and 100 ml of water. This solution is transferred to a 250.0 mL volumetric flask and water is added to the mark. Calibration standards are prepared adding to 5 different 50.0 ml volumetric flasks, 25.0 ml of the sample solution, and 0, 1, 3, 5, and 8 ml respectively of a standard sodium solution. The standard sodium solution has been prepared by dilution up to 100.0 mL of 20.0 ml of another solution that contains 0.2501 g Nacl in 1.0 L of water.

Q1: Discusion Q2: Purpose of experiment Q3: Introductionarrow_forwardMatch the detector with its description. A reverse bias is applied to a pn junction, which acts as a capacitor. Light strikes the surface, and holes and electrons are created which move towards the opposite charge. Accelerated electrons are emitted from a photosensitive surface and strike a second surface, knocking more than one electron from that surface and towards another surface. This process is repeated until there are more than 106 electrons collected per photon that strikes the first surface.
