Abstract
IN the issue of NATURE for January 31, p. 157, it has been stated that hydrated silica free from all impurities adsorbs acids. The amounts adsorbed by these samples are, however, small. We have since found that if thoroughly washed hydrated silica prepared from pure silicon tetrachloride be allowed to be partially dehydrated in air at room temperature, it shows a marked increase in its capacity to adsorb acids, as the following data will show:
