halogen

The light of halogen lamps is slightly more “whiteish” than incandescent lamps.

There is a group of closely allied elements to which the name halogen (salt-producer) has been given.

Compounds containing oxides and fluorides, &c., do not lend themselves to the method of determining the halogen by difference.

We may, in fact, consider that the descriptive study of the various halogen compounds dates from about this time.

The same absorbent quantitatively takes up any halogen and sulphur which may be present.

The same as Method 1, except that after ignition of the saponified mixture the halogen was determined by weighing as silver iodid.
