Important: Safety Warning
This page contains a formula or preparation using substances now known to be dangerously toxic, such as arsenic, mercury, lead, or cyanide compounds. Exposure to these substances can cause severe poisoning, permanent injury, or death.
In addition, this page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.

Chloric Acid
This is a yellowish liquid, smelling like nitric acid; it sets tralize with ammonia, and precipitate with a solution of 1 part of acetate of lead to every 72 parts of juice; filter, and again precipitate with nitrate of lead; allow the whole to stand until it forms a mass of crystals, then well wash, dry, powder, suspend in water, and decompose by a current of sulphuretted hydrogen; again filter, neutralize with ammonia, decolor with animal charcoal, a second time precipitate with nitrate of lead, and decompose the resulting nitrate of lead by sulphuretted hydrogen; lastly, filter, evaporate and crystallize. (Winckler.) Mr. Everett proposes the juice of the leaf-stalks of garden rhubarb as a source of malic acid. One imperial gallon of this juice contains 11,1394 grs. of dry malic acid. The stalks should be peeled before pressing out the juice, as the cuticle contains much color. Everett's process is as follows: Neutralize with hydrate of fire to paper or other dry organic matter. It lime, boil, filter, precipitate with nitrate of is a compound of chlorine and oxygen, and in lead, allow it to stand for a few hours, boil, combination with bases forms CHLORATES. cool, filter, decompose the precipitate with
