INTRODUCTORY NOTES. By means o£ Chemical Analysis we determine the composition of any substance. The object of Qualitative Analysis is to determine the nature o£ the constituents of a body. The object of Quantitative Analysis is to determine the amount of these constituents. Quantitative Analysis includes two methods, Gravimetric attid Volumetric Analysis. In Gravimetric Analysis we convert the lcno\vn cousritu- ents o£ a compound into such forms as will admit of their exact determination by weight. This is done chiefly in two ways : 1st By separating one of the constituents of a body as fuch {e.g., Cu by the battery), 2nd, By converting an existing constituent into a new form by e^cchange of elements {e.g., AgN03+HCl = AgCl +HNOj). The forms must fulfil two conditions: 1st Must be capable of being weighed exactly. 2nd, Must be of known atid fixed composition.
3j INTKODUCTOKV NOTES. The choice of form of precipitate depends on two comideratian.'S, The most preferable are— I St, Those most ii\solubIc in the surroundiiig liquid 2ml Those in which the proportion of the constituenti! to be determined is very smalt compared with the weight of the precipitate (t'.j^,, S In BaSO, is only T3.7 per cent.). In Volumetric Analysis the amount of a constituent is estimated by the action of reagents in solutions of known strength and of determined volumes. (Sec Notes on Vol- umetric Analysis, p. 40).
