Synthesis
Borderline hydrides are most commonly formed via the acidification or reduction of metal salts. For instance, cupric hydride is formed by reacting copper sulphate and hypophosphorous acid at about 70°C, forming a yellow precipitate that soon turns red-brown. Zinc hydride, ZnH2, can be formed by the reduction of either a zinc halide or dimethylzinc.

Famous quotes containing the word synthesis:
“It is not easy to construct by mere scientific synthesis a foolproof system which will lead our children in a desired direction and avoid an undesirable one. Obviously, good can come only from a continuing interplay between that which we, as students, are gradually learning and that which we believe in, as people.”
—Erik H. Erikson (20th century)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
“In order to begin an analysis, there must already be a synthesis present in the mind.”
—Johan Huizinga (1872–1945)
