Solutions are where most reactions occur because soluble compounds are separated from their rigid crystalline form and allowed to rotate and orient themselves on the molecular level to interact and ultimately react with their nearest neighbors. A process absolutely necessary for living systems.
(November 2013) Over 99% of all reactions occur in solution. Your very existence is the effect of billions of reactions happening every second in the bag of mostly water you call your body.
This podcast also demonstrates the calculations and procedure to create a proper solution in the laboratory.
