ELEMENTARY CHEMICAL MICROSCOPY 
{d) Fractionally sublime Naphthalene. 
(e) Fractionally sublime Indigo. 
4. Distillation. See page 292. {a) Use the apparatus shown in Fig. 153. 
Drive off NH3 from NH4CI, using NaOH. In the condensate test for NH, using 
H2PtClG (see page 327). 
ib) In like manner distil off CH3COOH from CH3COONa and H2SO4, using 
AgN03 (see page 421) as the test-reagent.
