溶于水，不溶于醇。稍有风化性。60℃时开始失水，加热至70℃失去结晶水,100℃成无水物。溶于5份水，溶于丙酮，不溶于乙醇和乙醚、醋酸乙酯、液氨。其溶液在光线及空气中易变质，不与热酸和浓酸混合或将溶液置于日光下，以防产生氰化氢。在溶液中含约0.2%碳酸钾，可稳定数月。低毒，半数致死量(大鼠，经口）1600-3200mg/kg。 六氰合铁酸钾 (II) 三水合物，通常称为亚铁氰化钾，是常用的抗结块剂。已经评估了其细胞毒性和遗传毒性作用。已经报道了在超疏水表面上的六氰基铁酸钾水溶液中的化学园的生长。研究了亚铁氰化钾在磷酸溶液中对低碳钢腐蚀的抑制效果。 高铁试剂(形成普鲁士蓝)。检定铁、铜、锌、钯、银、锇和蛋白试剂、尿液检验。点滴分析钯、锇、铀 六氰铁酸钾（II）三水合可用于通过氰形成干凝胶。这种胶可以用于固相气体传感器。 Potassium hexacyanoferrate(II) trihydrate, commonly known as potassium ferrocyanide, is a commonly used anticaking agent. Its cytotoxic and genotoxic effect has been evaluated. The growth of chemical garden in aqueous potassium hexacyanoferrate solution droplets on a superhydrophobic surface has been reported. The inhibition efficiency of potassium ferrocyanide in phosphoric acid solution against the corrosion of mild steel has been investigated. Potassium hexacyanoferrate(II) trihydrate is applied in formation of a xerogel via a cyanogel, the gel has potential use in solid-state gas sensors.
