将新测量的无定形二氧化硅溶解速率数据与文献中的数据相结合，生成一个方程，预测无定形二氧化硅的溶解通量（J，mol/m2 s）与温度（T，K）、钠浓度（mNa+，摩尔浓度）和氢离子活度的函数关系(aH+).J=14.6210-774002.303R1T+8.9510-777002.303R1TmNa+0.490aH+0.377相同的数据同样适合将溶解通量表示为温度、钠浓度和氢氧根离子活度函数的方程(aOH−).J=14.6210-774002.303R1T+1.73×10610-777002.303R1TmNa+0.490aOH-0.377 这些方程与石英方程具有相同的形式（Rimstidt，2015），表明钠离子对无定形二氧化硅溶解具有与石英相同的催化作用。
Newly measured amorphous silica dissolution rate data were combined with data from the literature to produce an equation that predicts the dissolution flux (J, mol/m2 s) of amorphous silica as a function of temperature (T, K), sodium concentration (mNa+, molal), and hydrogen ion activity (aH+).J=14.6210-774002.303R1T+8.9510-777002.303R1TmNa+0.490aH+0.377The same data fit equally well to an equation that expresses the dissolution flux as a function of temperature, sodium concentration, and hydroxide ion activity (aOH−).J=14.6210-774002.303R1T+1.73×10610-777002.303R1TmNa+0.490aOH-0.377These equations have the same form as those for quartz (Rimstidt, 2015) and show that sodium ions have the same catalytic effect on amorphous silica dissolution as they do for quartz.
