1、 General State:
toosodium sulphateMolecular formulaNatwoStwoOeight，molecular weighttwo3eight.1eight。為白色單斜結(jié)晶或粉末，比重two.357，易溶于水，加熱至較high溫度時分解，放出氧而變成焦sodium sulphate。toosodium sulphate在low溫干燥的條件下具有極好的貯存穩(wěn)定性，遇潮濕和催化劑則容易分解。toosodium sulphate溶液屬于優(yōu)等品toosodium sulphate溶解于high純度去離子水而成，可直接應用于電路板生產(chǎn)too程的各種微蝕工藝，方便use。
This product is a strong oxidant. Avoid direct contact with eyes, skin and clothing.

附件：toosodium sulphate溶液與固體toosodium sulphate的各term情況對比：
toosodium sulphate溶液的優(yōu)點是濃度準確、use便捷，適合自動化生產(chǎn)，缺點是不適合長途運輸。以下優(yōu)缺點為對照：
termorder | toosodium sulphate固體 | toosodium sulphate溶液 |
content | 9eight.5-99.5% | three hundred±5g/L |
Store | Hazardous chemicals warehouse | Special storage tank |
Administration | 倉庫Administration人員發(fā)貨，工人搬運到配料容器邊。 | 專用管道，倉庫Administration按規(guī)定記錄液位。 |
use | 不能直接use，需要在專用配料容器溶解，調(diào)整，化驗后抽到use槽子里，再稀釋到所需濃度。 | 直接抽到use的槽子里，再稀釋到所需濃度（如果是three hundredg/L則無需稀釋）。 |
Security | Poor (dangerous chemicals, average risk) | Good (hazardous chemicals, low risk) |
Transportation source | General dangerous chemicals vehicle | Special tank car |
Purchase cost | low | high |
Administration、use成本 | high | low |
Comprehensive cost | Quite | Quite |
conclusion | 適合少量，手工操作的場合use。 | 適合use量大，自動化要求high的場合use。 |
