1955年等研究了 Na(NH_4)_2[Ir(NO_2)_6]盐的生成条件,它在水中溶解度25℃时为6.70×10~(-3)摩尔/升。[Ir(NO_2)_6]~(3-)络离子很稳定,pH≈10时也不水解。但铱(Ⅲ)与亚硝酸根的络合物,研究得还不够。我们应用溶解度法重新研究了体
In 1955, the formation conditions of Na (NH_4) _2 [Ir (NO_2) _6] salt were studied. It was 6.70 × 10 -3 mol / L when the solubility in water was 25 ℃. The [Ir (NO_2) _6] ~ (3-) complex ions are stable and do not hydrolyze at pH≈10. However, the complexes of iridium (Ⅲ) with nitrite have not been studied sufficiently. We applied the solubility method to revisit the body
