New Raman spectra of NaS dissolved in hyper-concentrated NaOH(aq) and CsOH(aq) cast serious doubt on the widely-assumed existence of S(aq). To avoid conceptual and practical problems with sulfide equilibria in numerous applications, S(aq) should be expunged from the chemical literature. Thermodynamic databases involving sulfide minerals also need careful revision.
溶解于高浓度氢氧化钠水溶液(NaOH(aq))和氢氧化铯水溶液(CsOH(aq))中的硫化钠(NaS)的新拉曼光谱,对普遍认为的水合硫(S(aq))的存在提出了严重质疑。为避免在众多应用中硫化物平衡出现概念和实际问题,化学文献中应摒弃水合硫(S(aq))。涉及硫化物矿物的热力学数据库也需要仔细修订。
