| Abstract: | The content of silicon dioxide in silicate is determined by gravimetric analysis. With chistosan as coagulating agent.The factors which affect the coagulation of silicic acid are discussed. They arethe concentration of coagulating agent. solution acidity,the volume of evaporated solution,time and temperature The optimum precipitation conditions are given. standard sample is determined by the methodabove and the deviation of the result is low. |
