What are the differences between soluble and miscible? So far I found this (page 3 http://faculty.sites.uci.edu/chem1l/files/2011/03/D01MANmiscibility.pdf):

soluble=solid dissolves into a liquid

miscible=two liquid give rise to a homogeneous solution

Are there other differences?

Thank you.

    $\begingroup$ Solubility has certain limits; miscibility doesn't. Miscible liquids can mix in any proportion. Also, welcome to Chem.SE. $\endgroup$ Jan 28 '17 at 10:20

Your definition is basically correct, except using two liquids might provide for a clearer example than a solid and a liquid. For example, diethyl ether is soluble in water to about 7% at $\mathrm{20^oC}$. This does not mean that diethyl ether is partially miscible in water, but that it it partially soluble. This Wikipedia article provides a good distinction for miscibility:

Miscibility is the property of substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous solution.
