Analytical chemistry is a branch of chemistry concerned with ________

• Quantification, Identification, Minimisation

• Identification, Personalisation, Isolation

• Separation, Quantification, Identification

• Isolation, Quantification, Analysing

What type of analysis can you do in analytical chemistry?

• Quantitative & Qualification

• Quantitative & Quantification

• Quantification & Qualification

• Qualitative & Quantitative

What does qualitative analysis do?

• Identifies the nature of element or compound present in the sample

• Identifying how much of an element is in a sample

• Determines very small quantity of analyte

• Determines quantity of each and every constituent of the sample

Define quantitative analysis.

• Determines the spatial arrangement of atoms or identifies the functional group

• Determines the amount or concentration in a sample

• Determines each and every constituent of the sample.

• Identifies the element present in a compound

What is a sample?

• A portion of matter taken into the lab for analysis

• A portion of matter that makes up our body

• A known composition of matter

• A known substance taken into the lab for analysis
