or thereabouts.
The strength of milk of lime quoted in the above table was obtained by
carefully allowing 50 grammes of carbide to interact with 550 c.c. of
water at 5 deg. C. A higher degree of concentration of the milk of lime
was found by Hammerschmidt and Sandmann to cause a slight decrease in the
amount of acetylene held in solution by it. Hammerschmidt and Sandmann's
figures, however, do not agree well with others obtained by Caro, who has
also determined the solubility of acetylene in lime-water, using first, a
clear saturated lime-water prepared at 20 deg. C. and secondly, a milk of
lime obtained by slaking 10 grammes of quicklime in 100 c.c. of water. As
before, the figures relate to the volumes of acetylene dissolved at
atmospheric pressure by 100 volumes of the stated liquid.
