ANACHEM Flashcards
branch of science that deals with the separation, identification and determination of the components in a sample
Analytical Chemistry
particularly concerned with the questions of “what chemicals are present, what are their characteristics and in what quantities are they present?”
Analytical Chemistry
pertains to agreement of an experimental results with true value
accuracy
measure of reproducibility of data within a series of results
precision
T or F
All non-zero digits are significant ex. 23,579
True
T or F
All zeroes between non-zero digits are significant ex 2,305,079
True
T or F
All zeroes which are simultaneously to the right of the decimal point and at the end of the number are always signifivant ex 230.507900
True
T or F
Zeroes in between the decimal point and the first or last non-zero digits are not significant. ex 0.000239, 235,790,000
True
T or F
Type of analytical chemistry: qualitative and quantitative analysis
True
seeks to find elemental composition of inorganic compounds and the functional group of organic compounds
Qualitative
the measurements of quantities of substances produced in reactions rather than simply noting the nature of reactions
Quantitative
T or F
Qualitative chemistry: What? Identification, composition determination and ascertainment of impurities
True
T or F
Quantitative chemistry: how much? determination of the proportion of components in a substance
True
