Question

Two solutions are separated by a selectively permeable membrane. If one solution contains 10% NaCl and the other contains 30% NaCl, the 30% solution is: Option a) Hypotonic Option b) Isotonic Option c) Hypertonic Option d) Osmotic

Answer 1

In a combination of two different concentrated solutions separated by a selectively permeable membrane, the solution with a higher concentration, such as a 30% NaCl solution, is called hypertonic. Water tends to move from the solution with a lower concentration (hypotonic) to the hypertonic one due to osmosis.

Step-by-step explanation:

The question refers to two solutions of different sodium chloride (NaCl) concentrations separated by a selectively permeable membrane. In this case, the solution with 30% NaCl is termed hypertonic. Hypertonic refers to a solution's state where the concentration of solutes (in this case, NaCl) is higher than that of another solution, hence a hypertonic solution has a solute concentration higher than another solution.

In such a situation, water tends to move from the 10% NaCl solution (hypotonic solution) to the 30% NaCl solution (hypertonic solution) until an equilibrium is reached. This is a process called osmosis which is a form of passive transport that uses a concentration gradient to move water across a semi-permeable membrane.
