41. It forms colourless, dimorphous crystals at room temperature and is only slightly soluble in water. 42. It is only slightly soluble in water, but miscible with acetone, toluene and methanol. 43. The bipyridines are colourless solids, which are soluble in organic solvents and slightly soluble in water. 44. It is a colorless liquid that is slightly soluble in water, but miscible with organic solvents. 45. GeO 2 is only slightly soluble in acid but dissolves more readily in alkali to give germanates. 46. It dissolves in aqueous solutions of alkali hydroxides and carbonates but is very slightly soluble in water. 47. Quinoline is only slightly soluble in cold water but dissolves readily in hot water and most organic solvents. 48. Murexide in its dry state has the appearance of a reddish purple powder, slightly soluble in water. 49. This white crystalline solid is soluble in ethanol, slightly soluble in water and insoluble in diethyl ether. 50. Thus, are polar compounds always slightly soluble in nonpolar compounds, but not the other way round?
