Solubility of sodium chlorate in sodium hydroxide
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 20:07. A 45% sodium hydroxide solution was sampled from the large tank; it has no transparency. There is suspicion of excessive material concentration and precipitation. But it is not possible to determine what substance it is. It disappears after dilution with water and is transparent. I wonder if it’s sodium chlorate precipitating. Please help everyone. Thank you # , , &
You can do a test to determine the content of sodium chlorate.
Please list some of the analysis items – what exactly are they and within what scope do they fall?
Is it an ion-exchange membrane alkali or a diaphragm alkali? Have you analyzed the sodium chloride content?
If it’s a diaphragm alkali, it might be due to a high sodium sulfate content leading to precipitation
Ion-exchange membrane alkali. In ion-exchange membrane caustic, sodium chlorate, sodium chloride, sodium sulfate, and sodium carbonate are the substances that may precipitate. But I don’t know their solubility in 45% alkali. . . . .
