Question 5

Describe qualitative analysis

Answer 5

is when you compare qualities you observe to predetermined sample or pattern

Question 6

Describe quantative analysis

Answer 6

uses techniques that measure the quantity of a particular substance in a sample, it produces numbers with units such as grams and liters
