过硫酸钠外观为白色晶状粉末，无臭味。那么您知道过硫酸钠溶解度受哪些因素影响吗？

Sodium persulfate is white crystalline powder without odor. Do you know what factors affect the solubility of sodium persulfate?

过硫酸钠俗称过二硫酸钠；高硫酸钠。其相对密度（水=1）：2.4，其溶解性是溶于水，不溶于乙醇，在潮湿和高温能使分解加速；过硫酸钠呈酸性反应，能被乙醇和银离子分解；过硫酸钠也易潮解，在湿空气中和高温都能加速过硫酸钠分解，放出氧而变为焦硫酸钠。过硫酸钠具有强氧化性。

Sodium persulfate is commonly known as sodium persulfate; Sodium sulphate. Its relative density (water =1): 2.4, its solubility is soluble in water, insoluble in ethanol, and can accelerate decomposition in humidity and high temperature; Sodium persulfate is acidic and can be decomposed by ethanol and silver ions; Sodium persulfate is also prone to deliquescence. In wet air and high temperature, it can accelerate the decomposition of sodium persulfate, release oxygen and become sodium pyrosulfate. Sodium persulfate is highly oxidizing.

氢氧化钾厂家认为过硫酸钠溶解度主要受水温的影响，在水温为20℃时，过硫酸钠溶解度为549g/L。溶解度随着温度和湿度的升高而上升的。

Potassium hydroxide manufacturers believe that the solubility of sodium persulfate is mainly affected by water temperature. When the water temperature is 20 ℃, the solubility of sodium persulfate is 549g / L. Solubility increases with the increase of temperature and humidity.

过硫酸钠在任何温度下都会被分解，并且过硫酸钠分解速度随着温度和湿度的升高而加速。过硫酸钠在加热至180℃时会分解产物：H2SO4、O3、SO2、Na2SO4。过硫酸钠遇水会分解为硫酸钠和硫酸：Na2S2O7+H2O=Na2SO4+H2SO4。

Sodium persulfate will be decomposed at any temperature, and the decomposition rate of sodium persulfate will accelerate with the increase of temperature and humidity. Sodium persulfate will decompose products when heated to 180 ℃: H2SO4, O3, SO2, Na2SO4. Sodium persulfate will decompose into sodium sulfate and sulfuric acid when encountering water: na2s2o7+h2o=na2so4+h2so4.

过硫酸钠广泛用于照相业的废液处理，用作印刷电路板表面金属的软蚀剂及纺织用脱浆剂、硫化染料发色剂等。用作油井压裂液的破胶剂、电池去化剂及有机高分子乳化聚合引发剂。照相工业用于胶片显影、定影剂；还可用作废液处理剂、金属表面处理剂、印刷电路版的蚀刻剂等。
