Q. How are solutions classified as per to their comparative tonicity?
Comparative to another, a solution can be isotonic or isosmotic, hypotonic or hyposmotic or hypertonic or hyperosmotic. When a solution is fewer concentrated than another the adjective hypotonic is given and the more concentrated is known as hypertonic. When two compared solutions have the similar concentration both receives the adjective isotonic. So this classification makes sense merely for comparison of solutions.
