Note 7 — Chapter XX · SULPHUR, SELENIUM, AND TELLURIUM

One hundred parts of liquid carbon bisulphide, CS2, dissolve 16·5 parts of sulphur at -11°, 24 parts at 0°, 37 parts at 15°, 46 parts at 22°, and 181 parts at 55°. The saturated solution boils at 55°, whilst pure carbon bisulphide boils at 47°. The solution of sulphur in carbon bisulphide reduces the temperature, just as in the solution of salts in water. Thus the solution of 20 parts of sulphur in 50 parts of carbon bisulphide at 22° lowers the temperature by 5°; 100 parts of benzene, C6H6, dissolves 0·965 part of sulphur at 26°, and 4·377 parts at 71°; chloroform, CHCl3, dissolves 1·2 part of sulphur at 22°, and 16·35 parts at 174°.
