Preparing Solutions for Quantitative Work

Solutions are usually prepared in terms of their molar concentrations, e.g. mol l-1, or mass concentrations, e.g. gl 1. It should be noted that both of these refer to an amount per unit volume, i.e. concentration = amount/volume. It is important to use the highest (purity) grade of chemicals (liquids or solids) for the preparation of solutions for quantitative analysis, e.g. AnalaR or AristaR . For example, consider the preparation of a 1000 ppm solution of lead from its metal salt. [Pg.6]

Therefore, dissolve 1.5985 g of Pb(N03)2 in 1 vol% HN03 (AnalaR or equivalent) and dilute to one litre in 1 vol% HN03. This will give you a 1000 ppm solution of Pb. [Pg.6]
