100-00 122-5 1-984 1-814 The strength of the fuming acid is generally expressed as per cent, free CalculationsS03, but sometimes as total S03. When determining the strength by analysisit is most convenient to express it first as per cent. H2S04, and there are otheradvantages in expressing it thus. A figure is, of course, obtained which isgreater than 100, but it gives at once the quantity of sulphuric acid that willbe formed if 100 parts of it be added to a mixture, and if 100 be deducted fromit, the remainder is the amount of water that will disappear from the mixtureto form this sulphuric acid.
