improves establishes, extends, or develops new analytical methods to measure chemical phenomena
only follows the routine, daily application of the analytical method, not creating new and improved ones.
5- step analytical approach
define the problem, plan the analysis, conduct experiment, data analysis, report results
list the most common used fundamental units in class... AKA SI units
meters, kelvin, grams, and mol
moles of solute / Liters of solution
moles of solute formula / Liters of Solution
equivalents of solute / Liters of Solution
The first step prior to using any equipment in the laboratory
the most common analytical problem
how much was in there
The determination of chemical structure, of equilibrium
constants, of particle size, and of surface structure
identify what is present in a sample
to improve our understanding of the theory that supports an analytical method and to understand
better an analytical method's limitations.
the amount of one chemical species that reacts stoichiometrically with another chemical species.
the minor component that gets dissolved into the solution
the major component within a mixture, usually dissolves minor components
A deduction from gross weight made to allow for the weight of a container, to make measuring mass simpler
equipment designed to exclude additional moisture in the atmosphere to limit the amount of moisture is exposed to the object while cooling down.
rinse the beaker several times with small portions of water, adding each rinse to the volumetric
flask. Finally, add additional water to the volumetric flask's calibration
prepared by weighing out an appropriate portion of a pure solid or of a pure liquid, then
placing it in a suitable flask and diluting to a known volume.
the constant improvement toward existing procedures and equipment to best suit the situation
