Changes in the pH or concentration of sodium silicate solutions produce changes in the degree of polymerisation of the silicate species, and these have been followed by the technique of trimethylsilylation. Provided that the pH remains relatively high, above ca. 10 or 11 according to concentration, equilibrium is rapidly re-established after such changes. At lower pH, equilibrium is approached more
pH值或硅酸钠溶液浓度的变化会导致硅酸盐种类的聚合度发生变化,而三甲基甲硅烷基化技术则紧随其后。只要pH值保持相对较高(高于约3)。根据浓度在图10或图11中可以看到,在这种变化之后,平衡迅速恢复。在较低的pH值下,达到平衡的速度较慢,并且可以跟踪分布随时间的变化。
