Lesson 1 Flashcards
He introduced the
modern system of chemical symbols. He represented the
elements using one or two letters from their latin names.
Jöns Jakob Berzelius
It is a measurement science that consists of powerful ideas and methods that are useful in all fileds of science and medicine
AnaChem - Analytical chemistry
It is analysis that reveals the identity of
the elements and compounds in a
sample
Qualitative
It is an analysis that reveals the amount of
each substance
Quantitative
It is a method that measures the MASS of a SOLID analyte of compound chemically related to it
Gavimetric method
It determines the VOLUME of a LIQUID solution using a reagent
Volumetric
It is a method that involves the measurement of electrical properties such as voltage, current etc.
Electroanalytical methods
methods that are
based on measurement of
the interaction between
electromagnetic radiation
and analyte atoms or molecules or on the
production of such
radiation by analytes.
Spectroscopic Methods
Reyaaal or faaaake
The level of accuracy must be considered in picking a method
Real
It involves
obtaining a small mass of
material whose
composition accurately
represents the bulk of the
material being sampled.
Sampling
Reyal or faaakee
Sampling involves
obtaining a massive mass of
material whose
composition accurately
represents the bulk of the
material being sampled.
Faakee
Sampling involves
obtaining a SMALL mass of
material whose
composition accurately
represents the bulk of the
material being sampled.
It can be said that the material is ______ if it’s constituent parts can be distinguished visually or with the aid of of a microscope
Heterogenous
What is the opposite of heterogenous?
Homogenous
It is the process of determining how much of a given sample is the material indicated by its name.
Assay
It’s what you’re measuring
Analyte
It is the causes of error
Interference
Reyal or faaakeeee
Interference must not be eliminated
Fakeeee
These are all of the
components in the sample containing an
analyte
Matrix or sample matrix
