TABLE I.——_Multipliers and Standard Weights for the Principal Alkalies and their Carbonates._ (COOLEY.) KEY: A - Factors or Multipliers for converting the weight of carbonic acid expelled into real strengths. B - Quantity (in grains) to be taken, so that the per-centage value of the sample tested shall be shown in the terms of any of the denominations given, by the weight of the evolved Carbonic Acid reckoned—— C - in tenths of a grain. D - Whole numbers and decimals. E - Nearest common numbers. F - in quarter-grains. G - in half-grains. H - in grains. -----------------------+-------+-------------------------------------------+ | | B | | |--------------------^----------------------+ NAMES, &c | | C | | | | | |------^--------| | | | | A | D | E | F | G | H | -----------------------+-------+------+--------+---------+--------+--------+ AMMONIA | | | | | | | (pure, gaseous) | ·77273| 7·727| 7-3/4 | 19-1/3 | 38-5/8 | 77-3/0 | | | | | | | | Carbonate of ammonia | | | | | | | (neutral, anhydrous) |1·77273|17·727|17-3/4 | 44-5/16 | 88-5/8 |177-1/4 | | | | | | | | Carbonate of ammonia | | | | | | | (neutral, | | | | | | | crystallised) |1·9773 |19·773|19-3/4 | 49-7/16 | 98-7/8 |197-3/4 | | | | | | | | Sesquicarbonate of | | | | | | | ammonia (translucent) |2·6818 |26·818|26-13/16| 67-1/10 |134-1/10|268-1/5 | | | | | | | | Bicarbonate of ammonia | | | | | | | (crystallised) |3·5909 |35·909|35-9/10 | 89-13/16|179-5/8 |359-1/10| | | | | | | | POTASSA (anhydrous) |2·1364 |21·364|21-1/2 | 53-1/2 |107 |213-3/8 | | | | | | | | Hydrate of potassa |2·54546|25·455|25-5/11 | 63-5/8 |127-1/4 |254-1/2 | | | | | | | | Carbonate of potassa | | | | | | | (anhydrous) |3·1364 |31·364|31-3/8 | 78-1/2 |157 |313-1/2 |
