Identify the sample and analyte in each of the scenarios.

(a) Determination of the lead content in paint. lead paint

(b) Analysis of the nitrate content of soil near a local water source. soil nitrate

(c) Measurement of the citric acid found in a lime.

Identify the following as either sample or analyte.

(1) lead

(2) paint chips

(3) soil

(4) nitrate

(5) lime wedge

(6) citric acid

a) Analyte: lead. Sample: paint.

b) Analyte: nitrate. Sample: soil.

c) Analyte: citric acid. Sample: Lime

1) Lead: Analyte.

2) Paint chips: Sample.

3) Soil: Sample.

4) Nitrate: Analyte.

5) Lime wedge: Sample.

6) Citric acid: Analyte.

Explanation:

A sample is a portion of material selected from a larger quantity of material while an analyte is the chemical of the system that will be analysed.

Thus:

a) Analyte is lead while you must take a sample of paint to analyze this lead.

b) Analyte is the nitrate while sample must be soil.

c) Analyte is citric acid and lime is the sample

1) Lead: Analyte.

2) Paint chips: Sample.

3) Soil: Sample.

4) Nitrate: Analyte.

5) Lime wedge: Sample.

6) Citric acid: Analyte.
