Question

Solutions that have the same osmotic pressure are called _____ (isotonic/isometric) solutions.

Answer 1

Solutions that have the same osmotic pressure are called isotonic solutions. These are isosmotic solutions separated by a semipermeable membrane.

There is no transfer of solvent from one solution to another. These solutions have the same molar concentration. Blood is isotonic with 0.85% NaCl solution. Human RBCs are isotonic with 0.91 % NaCl solution.

Therefore, the correct answer is isotonic.
