Q.Which one of the following property of matter is Not quantitative in nature ? a. Mass b. Length c. Colour d. Volume

Analysis is always performed on a small representative sample rather than the entire bulk, and when only a few grams of solid or liquid are used, the procedure is called semi-microanalysis. Qualitative methods identify what a sample contains: classical techniques include separations (precipitation, extraction, distillation) followed by identification based on differences in colour, odour, melting point, boiling point or reactivity, and are carried out by either a dry method (sample examined undissolved, used as a quick preliminary test) or a wet method (sample dissolved first, then analysed, giving more definite results). Quantitative methods measure how much of a substance is present: for organic compounds this typically means finding the percentage of a constituent element or the concentration of a known compound in a sample, while for inorganic compounds it typically relies on gravimetric analysis (weighing the product of a decomposition reaction) or titrimetric/volumetric analysis (following a reaction between two solutions to completion and measuring the volume of reagent used). Only a handful of physical quantities — chiefly mass and volume — are actually measured directly in either approach, using equipment such as a weighing balance, burette or pipette.
