A device (10) for facilitating achemical reaction includes an upper member(12) having a predetermined configuration, alower member (14) having a predeterminedconfiguration, and a dissolvable member (16)disposed between and ultimately enclosed bysaid upper and lower members (12) and (14)such that upper and lower chambers (18) and(20) are formed having substantially equalvolumes. The upper chamber (18) ultimatelyreceives a dry sodium chlorite (30) and the lowerchamber (20) ultimately receives a dry acidmixture (32), whereupon, the upper and lowermembers (12) and (14) are joined, therebysealing the upper and lower chambers (18) and (20)and enabling the joined upper and lowermembers (12) and (14) to be disposed in water suchthat said lower member (14) engages the waterfirst. The joined upper and lower members (12)and (14) ultimately swell with absorbed wateruntil all water has been absorbed. The device(10) further includes a holder member (22) forreceiving a predetermined quantity of water andthe joined upper and lower members (12) and(14), whereby the upper and lower member (12)and (14) configurations cooperate to allow a predetermined quantity of waterto engage the dry sodium chlorite (30) and the dry acidmixture (32) to ultimately form slurries to dissolve the dissolvable member(16) to allow the slurries to engage and ultimately reactto generate chlorine dioxide gas that ultimately passes through the upper andlower members (12) and (14) and into a space to bedisinfected and/or deodorized.
