Dissolved silica is a major constituent of most natural waters; yet its significance in water quality transformations has remained largely undefined. It is thus important to develop systematic information regarding the effects of silica on the chemical and biologic characteristics of natural waters. In defining the role of dissolved silica in water quality transformations, it is essential first to obtain sufficient information regarding the chemical nature of the various species of silica which may exist under different conditions in dilute aqueous solution. This article describes some of the results of an investigation of several of the reactions of dissolved silica in dilute solution. (Author Modified Abstract)
