The Ozone-Iodine-Chlorate Clock Reaction
This work presents a new clock reaction based on ozone, iodine, and chlorate that differs from the known chlorate-iodine clock reaction because it does not require UV light. The induction period for this new clock reaction depends inversely on the initial concentrations of ozone, chlorate, and perchloric acid but is independent of the initial iodine concentration. The proposed mechanism conside...
متن کاملThe Chlorate-Iodine-Nitrous Acid Clock Reaction
A new clock reaction based on chlorate, iodine and nitrous acid is presented. The induction period of this new clock reaction decreases when the initial concentrations of chlorate, nitrous acid and perchloric acid increase, but it is independent on the initial iodine concentration. The proposed mechanism is based on the LLKE autocatalytic mechanism for the chlorite-iodide reaction and the initi...
متن کاملA clock reaction based on molybdenum blue.
Clock reactions are rare kinetic phenomena, so far limited mostly to systems with ionic oxoacids and oxoanions in water. We report a new clock reaction in cyclohexanol that forms molybdenum blue from a noncharged, yellow molybdenum complex as precursor, in the presence of hydrogen peroxide. Interestingly, the concomitant color change is reversible, enabling multiple clock cycles to be executed ...
متن کاملKinetics of the Treponema immobilization reaction under improved conditions.
The demonstration by Nelson and Mayer (1949) of an antibody in syphilitic sera that immobilizes virulent Treponema pallidum in the presence of complement in vitro led to the development (Nelson and Mayer, 1949; Nelson and Diesendruck, 1951) of a T. pallidum immobilization (TPI) test for use in the case of individuals who might repeatedly give a positive reaction to other tests for syphilis but ...
متن کاملSurface immobilization of biomolecules by click sulfonamide reaction.
Alkyne-modified biomolecules can be immobilized site- and chemoselectively on sulfonylazide slides under very mild conditions by means of the click sulfonamide reaction.
