摘要: Abstract The law that the incubation period of precipitation, for a certain electrolyte, is proportional to some (negative) power ionic product (1–4) found be valid AgCl, Ag2CrO4, CaC2O4, CaF2, and KClO4, but not BaSO4. equation Johnson O'Rourke (8) rate precipitation da dt = Ka q (1−a) p , where α degree reaction, t time, K, q, are constants which can determined experimentally ( 2 3 ; or 4 ), integrated BaSO4, SrSO4, whereas it only partly CaF2. p] agreement seems indicate controlled by chemical reaction in surface growing crystals rather than diffusion.
