I think it means that it dissolves when in water long enough.
Something that can be dissolved in water is said to be soluble.
no some materials are soluble but not gels. Like salt which is soluble
It means "not". Something in-credible is not able to be believed, and in-soluble cannot be dissolved.
Something that can dissolve. A substance that is water-soluble can be dissolved in water.
Something that is soluble can dissolve in a liquid (like sugar in water), but something that insoluble cannot (like rocks in water).
Water is a substance. If you put it together with something soluble, it becomes a solution. With something non-soluble, it becomes a mixture.
Soluble means a substance can be dissolved. For example, salt is soluble in water. It is able to be dissolved.
I'm not sure what you mean by "solible". If you meant "soluble," it refers to a substance's ability to dissolve in a liquid. If you meant something else, please provide more context.
The word "soluble" (in science) refers to something that can dissolve in something else, like salt in water. The word "insoluble" refers to something that does not dissolve in something else, like oil in water.
The antonym of soluble is insoluble. Something that is insoluble does not dissolve in a particular solvent.
More soluble in what? What is the SOLVENT? If you mean which is most soluble in WATER, then it would certainly be salt, if by salt, you mean sodium chloride.
Assuming you mean ascorbic acid, or vitamin C, it is water-soluble.
