Copper(I) chloride is a pure substance.
Copper chlorides (CuCl and CuCl2) can be obtained as very pure compounds.
A blue liquid can be classified as a heterogeneous mixture, a solution, or a pure substance depending on its composition. If the blue color comes from a uniform distribution of a dye in a solvent, it is likely a homogeneous solution. If the blue color results from suspended particles or separate phases, it would be a heterogeneous mixture. If the liquid is a single chemical compound that is blue in color, then it would be considered a pure substance.
A pure substance is a substance that cannot be separated by physical means. To determine whether a substance is pure, let a container of it evaporate. If there is no residue then the substance is pure.

Methane is a pure substance.
Yes, methylene blue is considered a pure substance when it is in its isolated chemical form, typically as a crystalline solid. It has a specific chemical formula (C16H18ClN3S) and consistent properties, such as melting point and solubility, that define it as a pure compound. However, in practical applications, it may be found in mixtures or solutions, which would not classify those as pure substances.
