| 由于铬酸钠基本不溶于甲醇，易溶于水，因此本文测定了铬酸钠在甲醇-水混合溶剂中的溶解度。同时，由于铬酸钠在上述溶剂中的溶解速率会随着浓度的 增加而变慢，接近饱和时十分缓慢，测定的过程需要较长时间，因此，本文采用平衡法测定铬酸钠的溶解度。 |

| In this the solubility of sodium chromate in methanol - water mixed solvent is measured since sodium chromate is basically insoluble in methanol but soluble in water. In addition, the solubility of sodium chromate is determined with the balanced method because the rate of dissolution of sodium chromate in the above mentioned solvent becomes slow progressively as a function of the increased concentration of sodium chromate, being extremely slow when the concentration of sodium chromate is approaching saturation, making it takes a very long time to perform the tests. |

| As sodium chromate can’t dissolve in methyl alcohol, but easily in water, the author measures the solubility of sodium chromate dissolving in mixed solvents of methyl alcohol and water. Meanwhile, dissolution rates of sodium chromate in above solvents usually decrease with the increase of the concentration, and when it is near saturated, the rate is really very slow, and thus the time required for measuring is comparatively long. Therefore, for this shortcoming, the balance method is utilized for measuring the solubility of sodium chromate in this paper. |
