可溶性与不溶性
材料在溶剂中的溶解度和不溶性非常重要。它甚至是地球上生命及其延续的基本现象。应该有各种化学和物理相互作用,以使物质可溶和不溶性。在这里,我们将从更广泛的角度考虑这两个术语。
易溶
溶剂是具有溶解能力的物质,因此可以溶解另一种物质。溶剂可以处于液体,气态或固态。溶质是一种可溶于溶剂的物质,以形成溶液。溶质可以处于液体,气相或固相。因此,溶解度/可溶性是溶质溶于溶剂中的能力。溶解度的程度取决于各种因素,例如溶剂和溶质的类型,温度,压力,搅拌速度,溶液的饱和水平等。只有在它们是相似的情况下,溶液的饱和度,溶液的饱和度,溶液的饱和水平(“喜欢溶解喜欢”)。例如,极性物质可溶于极性溶剂,而不是非极性溶剂。糖分子之间的分子间相互作用弱。当溶解在水中时,这些相互作用将破裂,分子将分开。债券断裂需要能量。 This energy will be supplied by the formation of hydrogen bonds with water molecules. Because of this process, sugar is well soluble in water. Similarly, when a salt like sodium chloride dissolves in water, the sodium and chloride ions are released, and they will interact with polar water molecules. The conclusion we can arrive from the above two examples is that, the solutes will give their elementary particles upon dissolving in solubility. When a substance is first added to a solvent, first it will dissolve rapidly. After sometime, a reversible reaction establishes, and the dissolving rate will decrease. Once the dissolving rate and the precipitating rate are equal, the solution is said to be at solubility equilibrium. This type of solution is known as a saturated solution.
无法解决
不溶性意味着无法溶解。它与可溶性相反。如上所述,如果物质彼此“喜欢”,它们会彼此溶解。当他们“不喜欢”彼此时,他们就不可溶。换句话说,如果两种物质无法彼此相互作用,它们将不会可溶。例如,极性物质和非极性物质彼此不喜欢。因此,它们之间没有任何互动。因此,非极性溶质不会溶于极性溶剂。例如,一块橡胶不能溶于水。否则糖不溶于油。 Insoluble material can be separated easily by filtration method. As there are substances which are completely insoluble, there can be some which are partly soluble. If the solute and the solvent can make interactions for some degree, they are partly soluble.
What is the difference between Soluble and Insoluble? • Soluble means capable of dissolving in a solvent whereas insoluble means incapable of dissolving in a solvent. •极性物质和非极性物质分别可溶于极性和非极性溶剂,而彼此混合时极性和非极性物质则不溶。 •当溶质溶于溶剂,他们可能make a homogenous mixture, but if they are insoluble they may not. •混合物中不溶性组件的分离要比分离可溶性组件更容易。 |
