URGENT: ISE methods problem: is it possible to make sodium sulfide nanohydrate from sodium sulfide?

20 August 2018 1 5K Report

Hello, I am using probes and for calibration I was supposed to use sodium sulfide nanohydrate but my order came wrong and I have only sodium sulfide (Na2S) or sodium sulfide hydrate 60% (H-Na2S) s426 on fisher). Can I make one product fron the other without much difficulties? thanks
