under alkaline situation, the hydrolyze rate is high, the pariticles of silicon oxide is easy to gather, so the solution is suspending. under acid situation, the hydrolyze rate is low, the particle is hard to gather, so the solution is transparent. the limpidity depends on the PH value, the optical range is 3 to 4. the regulator of PH must be strong acid, if it is weak acid, it is easy to suspend |
