analyte

Examples of analyte in the following topics:

• Redox Titrations

  • Redox titration determines the concentration of an analyte containing either an oxidizing or a reducing agent.
  • A standardized 4 M solution of KMnO4 is titrated against a 100 mL sample of an unknown analyte containing Fe2+.
  • What is the concentration of the analyte?
  • Now that we know the number of moles of iron present in the sample, we can calculate the concentration of the analyte:
  • Calculate the concentration of an unknown analyte by performing a redox titration.

• Strong Acid-Strong Base Titrations

  • The reactant of unknown concentration is deposited into an Erlenmeyer flask and is called the analyte.
  • The indicator—phenolphthalein, in this case—has been added to the analyte in the Erlenmeyer flask.
  • Step 2: Use stoichiometry to figure out the moles of HCl in the analyte.

• The Study of Chemistry

  • As one of the natural sciences, chemistry provides scientists with insight into other physical sciences and powerful analytical tools for engineering applications.
  • Analytical chemistry seeks to determine the exact chemical compositions of substances.

• Description of the Hydrogen Atom

  • The hydrogen atom (consisting of one proton and one electron, not the diatomic form H2) has special significance in quantum mechanics and quantum field theory as a simple two-body problem physical system that has yielded many simple analytical solutions in closed-form.
  • The solution to the Schrödinger equation for hydrogen is analytical.
  • In most such cases, the solution is not analytical and either computer calculations are necessary or simplifying assumptions must be made.

• Acid-Base Titrations

  • Alkalimetry, or alkimetry, is the specialized analytic use of acid-base titration to determine the concentration of a basic (alkaline) substance; acidimetry, or acidometry, is the same concept applied to an acidic substance.
  • Place an accurately measured volume of the analyte into the Erlenmeyer flask using the pipette, along with a few drops of indicator.

• Amorphous Solids

  • At an atomic scale, it is difficult to distinguish between the two different types, even using advanced analytical techniques such as x-ray diffraction and transmission electron microscopy.

• Combustion Analysis

  • Combustion analysis is an elemental analytical technique used on solid and liquid organic compounds.

• Major Features of a Phase Diagram

  • The phase of a system is generally defined as the region in the parameter space of the system's thermodynamic variables (for immediate purposes, in the pressure-temperature parameter space) in which the system's free energy is analytic (meaning it can be calculated exactly from known parameters of the system).

• Strong Acid-Weak Base Titrations

  • A known volume of base with unknown concentration is placed into an Erlenmeyer flask (the analyte), and, if pH measurements can be obtained via electrode, a graph of pH vs. volume of titrant can be made (titration curve).

• Particle in a Box

  • The particle in a box model provides one of the very few problems in quantum mechanics which can be solved analytically.
