What is quantitative analysis?
AFinding how much of a substance a sample holds
BFinding which elements a given sample holds
CFinding the boiling point of a liquid sample
DFinding the colour change of an added dye
Answer & Solution
Correct answer: A. Finding how much of a substance a sample holds
1. Quantitative analysis asks how much of a substance is present, not merely whether it is present.
2. The answer may be an amount or a concentration.
3. Titration finds it from the volume of a reagent that reacts completely with the sample.
4. Gravimetric methods find it from the mass of a product formed instead.
