Solution A is hyperosmotic means:

- The osmolarity of Solution A is higher than that of Solution B (The concentration of solute particles in Solution A is higher than that of Solution B.)

Solution A is isosmotic means:

- The osmolarity of Solution A is the same than that of Solution B (The concentration of solute particles in Solution A equals that of Solution B.)

Solution A is hyposmotic means:

- The osmolarity of Solution A is lower than that of Solution B (The concentration of solute particles in Solution A is lower than that of Solution B.)
