The hydrosol may be obtained in the solid state, completely soluble in warm water. This is most readily accomplished by concentration over sulphuric acid in vacuo of the colloidal solution obtained by reducing a platinum salt with hydrazine hydrate in the presence of a protective colloid, such as gum acacia.
