Here's why:
* Solubility is relative: The ability of one substance to dissolve in another depends on the chemical properties of both substances. Some substances are more soluble in certain solvents than others.
* Water, the "universal solvent": While water is often called the "universal solvent" due to its ability to dissolve a wide variety of substances, it cannot dissolve everything. For example, oils and fats are not soluble in water.
* Limits to solubility: Even the most powerful solvents have limitations. For instance, some substances, like diamonds, are incredibly difficult to dissolve.
So, what does "universal solvent" actually mean?
It's more accurate to say that a "universal solvent" is a substance that can dissolve a wide variety of materials. Water is a good example of this, but it's not the only one.
It's important to note: The term "universal solvent" is often used in a casual way, and it's important to remember that no single substance can truly dissolve everything.
