硒酸
制 备
[编辑]SeO2 + H2O2 → H2SeO4
无水硒酸
硒酸也可以通过亚硒
另一种制备硒酸的方法是将单质硒
Se + 4 H2O + 3 Cl2 → H2SeO4 + 6 HCl
化学 性 质
[编辑]类似
硒酸
- H2SeO4 + 2 H+ + 2 Cl− → H2SeO3 + H2O + Cl2
硒酸
- 2 H2SeO4 → 2 H2SeO3 + O2
硒酸
- H2SeO4 + 2 HSO3F → SeO2F2 + 2 H2SO4
热的浓硒
- 2 Au + 6 H2SeO4 → Au2(SeO4)3 + 3 H2SeO3 + 3 H2O
- 2 Au + 4 H2SeO4(浓) → Au2(SeO3)2(SeO4) + H2SeO3 + 3 H2O
