instrumental analysis quiz 1

wet method

the use of volumetric or gravimetric titrations to solve a specific analytical problem

critical angle

the precise angle in refractometry that gives the optimum refractive index volume

voltage

the potential of a battery when there is an interaction of galvanic cells

conductivity

the measure of the total electrolytes in a solution

oxidation

occurs at anode (-), loss of electrons

reduction

occurs at cathode (+), gain of electrons

galvanic cell

current flows spontaneously because of strong redox tendency

electrolytic cell

electric energy used to force non-spontaneous chemical reactions

battery

package of one or more galvanic cells used for the production and storage of electric energy by chemical means

Nd^20

the refractive index @ 20 deg C with light at the sodium D line of a particular medium

refraction

bending of light as it changes media

absorption

incoming radiation absorbed through various wavelengths

emission

energy into a sample then the sample emits light (glow in the dark)

electrogravimetry

a method used to separate and quantify ions of a substance, usually a metal. In this process, the analyte solution is electrolyzed.
