True
False
Analytical chemistry is involved in establishing economic value.
True
True
When a method produces a few interferences, such methods are considered to be?
Robust
Specific
Rugged
Selective
Anna, a chemist, is unfamiliar with the samples she collected. What kind of analysis should she perform to identify the constituents present?
Fundamental analysis
Characterization analysis
Qualitative analysis
Quantitative analysis
The sample for the analysis should be representative and homogenous.
True
False
A sample was mixed with a flux and heated in a crucible until molten before being dissolved in a dilute acid. What dissolution technique is employed?
Fusion
Use of Non-oxidizing acid
Use of oxidizing acid
Organic Solvents
The following should be considered when determining the size of the sample: analyte concentration, specific steps, and equipment to be used.
True
False
A result is hugely significant in an experiment. Give at least one way to improve confidence in the final results.
It is defined as a method of eliminating interferences from a substance by converting it to a noninterfering form.
Which of these statements is true?
I. The procedure used to calculate the amount or concentration of analyte depends on the analysis method.II. Some methods do not rely on absolute measurements (concentration is determine directly from the measured value)
III. Some methods rely on relative measurements (concentration is determine by comparison of the measured value for the unknown with similar values obtained for known amount of analyte)
IV. Evaluate the results – evaluate how good or how certain the data is
