What reading level is Laboratory Experiments in General Chemistry book?
To quickly assess the difficulty of the text, read a short excerpt:
168 in which sulphur was melted in a Hessian crucible.
170. Sulphur Monochloride (S 2 C1 2 ). Arrange an apparatus as shown in Fig. 25. The distilling flask should contain about 30 gms. Of sulphur. Generate chlorine by means of MnO 2, NaCl and H 2 SO4 and pass the gas into the distilling flask as shown. The second distilling flask, which acts as a condenser and receiver, is cooled by means of a stream of water.
When the stream of chlorine becomes regular, heat the distilling flask to melt the s...ulphur and to distill the S 2 C1 2 formed. The thermometer shows the temperature of the vapor of the latter. Do not let the temperature rise above 160 or 170.
When sufficient S 2 C1 2 has been obtained, stop the operation and thoroughly clean and dry the distilling flask. Then introduce the S 2 C1 2 and stopper the flask with a cork carrying only a thermometer. Connect the apparatus as shown and redistill the liquid, being careful to note the temperature at which it distills.
171. Describe fully the properties of sulphur mono- chloride.
