Abstract

Summary Evidence is found that semicarbazide acetate, a salt of the ammonium type, is incompletely dissociated in aqueous solution, from the dependence of the rate of semicarbazone formation on acetic acid concentration. 2. The dissociation constant of this salt into molecules has the approximate value 0.12, both at 25 and at 0". 3. Consequences of this new equilibrium effect, for semicarbazone preparation and for the mechanism of the ...
