Sulphuric acid dissolves it without the production of it red-brown, bromine produces a colour, and chlorine and ammonia beautiful purple colour, water give no murexide reaction.
The formation of murexide is used as a test for the presence of uric acid, which on evaporation with dilute nitric acid gives alloxantin, and by the addition of ammonia to the residue the purple red colour of murexide becomes apparent.
We are not aware that murexide has yet been brought forward as a pigment, and judging from its character as a dye, it would scarcely enrich the palette.

Murexide is produced by the action of ammonia on alloxan, which is itself derived from the uric acid of guano by treatment with nitric acid, and was known nearly forty years back to stain the fingers and nails red.
When an alkaline solution of murexide is precipitated by an acid, a light shining powder results, called purpuric acid.
Murexide is turned, by potassa, gray in its light shades and violet in its dark ones.

All those parts, in fact, which lie immediately under the translucid skin are covered with a layer of pigment which can be turned into murexideand is identical in nature with the white powder of the adipose lace.
Treated with nitric acid, the adipose tissue of the Decticus produces an effervescence similar to that of chalk and yields enough murexide to redden a tumblerful of water.
Dissolved in water, the murexide derived from uric acid is a magnificent crimson.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "murexide" in a variety of sentences. We hope that you will now be able to make sentences using this word.
