Journ.'). The use of carbonate of soda is also cheaper than all other above-mentioned substances. One milligramme equivalent sulphate of lime in 1 litre = 68 grm, sulphate of lime in 1 cub. m. requiring for decomposition: 120 gr. (68-88 per cent.) chloride of barium of commerce - cost, 0.6d. Or 50 gr. magnesia preparation - cost, ½d. Or 55 gr. (96-98 per cent.) carbonate of soda - cost, 0.41d. The proportions of cost by using chloride of barium, magnesia preparation, carbonate of soda will be 6: 5: 4. Рядом со словом boiler incrustation, magnesia в knolik
