Rohrbach's solution, an aqueous solution of barium and mercuric iodides, introduced by Carl Rohrbach, has a density of 3.588.
The aqueous solution of ammonia is very basic in its reactions, and since it is a weak electrolyte, one must assume the solution to contain a certain amount of ammonium hydroxide NH 4 OH, although it is probably chiefly composed of a solution of ammonia in water.
Concentration of the aqueous solution in a desiccator gives a deposit of crystals of a very deliquescent salt, H21n2(S04)4.8H20.
Its aqueous solution has a faint sweet taste, and is dextro-rotatory, the rotation of a fresh solution being about twice that of an old one.
Eltekow, Ber., 1878, 11, p. 414); by the action of metals on the halogen compounds Cn.H 20 Br 2 i by boiling the aqueous solution of nitrites of the primary amines (V.
An aqueous solution readily dissolves lead oxide, with formation of a strongly alkaline solution containing basic acetates (Acetum Plumbi or Saturni).
It forms yellow crystals soluble in water; the aqueous solution on standing gradually depositing a basic salt.
Barium bromate, Ba(Br03)2, can be prepared by the action of excess of bromine on barytawater, or by decomposing a boiling aqueous solution of loo parts of potassium bromate with a similar solution of 74 parts of crystallized barium chloride.
Weith, Ber., 1882, 15, p. 1513), and by the spontaneous hydrolysis of an aqueous solution of cyanogen gas.
By the action of sodium amalgam on an aqueous solution of the acid, benzyl alcohol, tetrahydrobenzoic acid and hexahydrobenzoic acid are formed.
