The law of conservation of mass states that mass is neither created nor destroyed by chemical reactions or physical transformations. according to this, the mass of the products must equal the mass of the reactants.
The word isotonic is used to refer to the solutions (two solutions) which have the same osmotic pressure in both sides of the semipermiable membrane. The condition allows the free movement of water across the membrane. However, this does not change the concentration of the solution across the membrane.
Hence, osmosis may not occur in this condition.
