過(guò)硫酸鈉外觀為白色晶狀粉末,無(wú)臭味。那么您知道過(guò)硫酸鈉溶解度受哪些因素影響嗎?

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

過(guò)硫酸鈉俗稱(chēng)過(guò)二硫酸鈉;高硫酸鈉。其相對(duì)密度(水=1):2.4,其溶解性是溶于水,不溶于乙醇,在潮濕和高溫能使分解加速;過(guò)硫酸鈉呈酸性反應(yīng),能被乙醇和銀離子分解;過(guò)硫酸鈉也易潮解,在濕空氣中和高溫都能加速過(guò)硫酸鈉分解,放出氧而變?yōu)榻沽蛩徕c。過(guò)硫酸鈉具有強(qiáng)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.

氫氧化鉀廠家認(rèn)為過(guò)硫酸鈉溶解度主要受水溫的影響,在水溫為20℃時(shí),過(guò)硫酸鈉溶解度為549g/L。溶解度隨著溫度和濕度的升高而上升的。

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.

過(guò)硫酸鈉在任何溫度下都會(huì)被分解,并且過(guò)硫酸鈉分解速度隨著溫度和濕度的升高而加速。過(guò)硫酸鈉在加熱至180℃時(shí)會(huì)分解產(chǎn)物:H2SO4、O3、SO2、Na2SO4。過(guò)硫酸鈉遇水會(huì)分解為硫酸鈉和硫酸: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.

過(guò)硫酸鈉廣泛用于照相業(yè)的廢液處理,用作印刷電路板表面金屬的軟蝕劑及紡織用脫漿劑、硫化染料發(fā)色劑等。用作油井壓裂液的破膠劑、電池去化劑及有機(jī)高分子乳化聚合引發(fā)劑。照相工業(yè)用于膠片顯影、定影劑;還可用作廢液處理劑、金屬表面處理劑、印刷電路版的蝕刻劑等。
