very slightly soluble

appearance: white or almost white crystalline powder, almost no solution in water, soluble in ether, very slightly soluble in ethanol.

性状：白色或类白色结晶性粉末，几乎不溶液水，溶于乙醚，极微溶于乙醇。

The dependence of the adsorbability of slightly water soluble metal compounds on the pH value of the solution is very similar to that with activated carbon as adsorbent.

难溶金属化合物在树脂上的吸附率与溶液pH值的关系与采用活性碳作吸附剂的情况十分相似。

Mn2+ in weak base can creat red chelate which is very slightly soluble. Under gelatin's presence, suspended matter forms diaphaneity, homogeneous and stable, colored sol.

当Mn2+在弱碱性中（pH为9～10）反应生成难溶于水的红色螯合物，悬浮物在明胶存在下形成透明、均匀、稳定的有色溶胶。

DBM is white or light yellow crystalline powder, soluble in ether, chloroform, xylene, toluene and sodium hydroxide solution, slightly soluble in ethanol, very slightly soluble in water.

本品为白色或浅黄色结晶粉末，易溶于乙醚，氯仿，二甲苯，甲苯及氢氧化钠水溶液，微溶于乙醇，极微溶于水。
