Analytical Chemistry 1 Mock Test (Part I)

It indicates the amount of each substance in a sample

• Analysis

• Quantitative Analysis

• Qualitative Analysis

• Analytical Method

• Sampling method

This method is used to determine the mass/weight of the analyte or some compound chemically related to it

• Volumetric method

• Electroanalytical method

• Spectroscopic method

• Gravimetric method

• Scientific Method

These are components of a sample that are determined

• Analyte

• Sample

• Solvent

• Solution

• Reactant

It is a process of collecting a small mass of a material whose composition accurately represents the bulk of the material being sampled

• Assay

• Processing

• Sample

• Sampling

• Analyzing

It is a process of determining the proportionality between analyte concentration and a measured quantity

• Sampling

• Analyzing

• Calibration

• Calibrating

• Assay

It is a process of determining how much of a given sample is the material by its indicated name

• Assay

• Sampling

• Analyte

• Calibration

• Matrix

This is recommended because loss or gain of water changes the chemical composition of solids

• Drying samples

• Mixing samples

• Replicating samples

• Selecting samples

• Analyze samples

these are portions of a material of approximately the same size that are carried through an analytical procedure at the same time and in the same way

• Replicates

• Replace

• Samples

• Replica

• Replicate samples

It is a species that causes an error in an analysis by enhancing or attenuating the quantity being measured

• Interfering

• Chemical Error

• Interference

• Error

• Eliminating

It is the collection of all the components in the sample containing the analyte

• Analyte

• Assay

• Sample

• Sample Matrix

• Matrices
