• Volumetric analysis determines the volume of a solution containing a sufficient reagent to react completely with the analyte.
• Electroanalytical analysis involve the measurement of electrical properties
• Gravimetric analysis determines the mass of the analyte
• The steps in quantitative analysis are: Picking a method, acquiring the sample, processing the sample, eliminating interferences, and sampling.
• Macro analysis: used for samples whose masses are greater than 0.1g
• Semimicro analysis: 0.01 to 0.1g
• Micro analysis: 10^-4 to 10^-2g
• Ultramicro analysis: less than 10^-4g
• A material is said to be heterogeneous if its constituent parts can be distinguished visually
• Analyte Level: 100%, Type of Constituent: Major
• Analyte Level: < 1 ppb, Type of Constituent: Ultratrace
• Analyte Level: 1ppb to 100ppm, Type of Constituent: Trace
• In reading the measurement of a buret, the bottom meniscus is correct.
• Precipitates from gravimetric analyses are commonly collected by filtration.
• Burets are precisely manufactured glass tubes with graduations enabling you to measure the volume of liquid delivered through the stopcock at the bottom.
