Bado solution required for precipitating the sul-phuric acid. This is equivalent to *0445 S03 or *890f° S03. In the estimation of sulphates in solution containingmagnesium or other metals it is advisable to precipitatethese by means of the mixture of hydrate and carbonateof potash and work upon the filtrate. 4- Journal Royal Society of N.
