EVERYDAY SCIENCE

Detailed explanation-1: -Replicate samples, or replicates, 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.

Detailed explanation-2: -Replicates are samples of about the same size that are carried through an analysis in exactly the same way.

Detailed explanation-3: -Gravimetric methods: determine the mass of analyte or some compound chemically related to it. 2. Volumetric methods use the volume of a solution containing sufficient reagent to react with the analyte.

Detailed explanation-4: -Interference or Interferent – a species that causes an error in the analytes Matrix or sample matrix – collection of all components in the samples containing the analyte. Calibration – process of determining the proportionality between analyte concentration and quantity.

Detailed explanation-5: -An analyte, component (in clinical chemistry), titrand (in titrations), or chemical species is a substance or chemical constituent that is of interest in an analytical procedure. The purest substances are referred to as analytes, such as 24 karat gold, NaCl, water, etc.
