求翻译：性状：无色晶体或白色粉末。有吸湿性。密度2.33。在180℃时失去二分子结晶水，300℃时失去全部结晶水。性质与焦磷酸钠相像，但溶解度较大。溶于水，不溶于乙醇是什么意思？

Properties: colorless crystal or white powder. Hygroscopicity. Density of 2.33. At 180 ℃, loss of two molecules of crystal water, 300 ℃ when the loss of all the crystal water. Similar nature and pyrophosphate, but the greater solubility. Soluble in water, insoluble in ethanol

: Colorless crystal or white powder. There is a moisture absorption. Density 2.33 . When the 180° C crystalloid, lost 2 elements at 300 ° C lose all the crystalloid. Like nature and Sodium Pyrophosphate solubility, but larger. Soluble in water, insoluble in ethanol

Character: Colorless crystal or white powder.Has the water absorbability.Density 2.33.When 180℃ loses two molecular crystal water, 300℃ when loses the complete crystal water.The nature and the sodium pyrophosphate resemble, but the solubility is big.Dissolves in the water, does not dissolve in the e
