Mercurous nitrate spray

Mercurous nitrate spray. Barbiturates give dark spots which fade slowly with some dilute solutions the spots de rapidly. [Pg.168]

Acidified potassium permanganate solution. Yellow-brown spots on a violet badcground are givoi by drugs with unsaturated aliphatic bonds, e.g. quinalbarbitone. This solution may be used to overspray a plate which has been previously sprayed with mercurous nitrate spray. [Pg.168]
