If a substance is dissolved in a solvent does it still oxidise? Does it depend on weather the solvent can dissolve oxygen?

Not only can things be oxidized in solution, but in some cases (such as ferrous chloride) exposure to air can contaminate your solution with oxidation products. Such solutions should be stored in a way that prevents or at least retards air from getting in (e.g., taping around the lid).
