What is the solute and solvent of biogas?

Answer 1

In biogas, the primary components are methane and carbon dioxide, with methane being the main energy-carrying gas. In this context, the solvent can be considered the gaseous mixture itself, while the solutes would typically be the trace gases (such as hydrogen sulfide, ammonia, and volatile organic compounds) present in smaller amounts. However, biogas is primarily a gas mixture rather than a solution in the traditional sense, as it does not involve a liquid solvent dissolving a solid or liquid solute.
