In the presence of either neutral salts, basic salts or acids the iodine absorbed increases rapidly and reaches a maximum in about 2-10 minutes after which iodine appears to he liberated at a higher rate than that at which it is absorbed and hence the apparent absorption of iodine falls In neutral solution, the liberation of iodine takes place slowly, although as a general rule neutral salts have no appreciable effect on the course of this reaction The absorption of iodine appears to be fairly rapid and continuously increases with time in the presence of basic salts In the presence of mineral acids, the primary absorption of iodine is very small, being only about 1/5th of that required in the ease of neutral salts The liberation of iodine in the second stage, under these conditions, is more rapid In the presence of acetic acid, the absorption is similar to that in the case of neutral salts The absorption of iodine is slightly more in an atmosphere of carbon dioxide than under ordinary conditions |
