Amount of a substance (called the solute) that dissolves in a unit volume of a liquid substance (called the solvent) to form a saturated solution under specified conditions of temperature and pressure.Solubility is expressed usually as moles of solute per 100 grams of solvent.

Each of the following solutions is separated from a solution containing pure water with a semipermeable membrane. Assuming they
liberstina [14]

Answer:

Osmotic pressure is a measure of a solution's tendency to attract or take in water from another solution when the two solutions are separated by a semipermeable membrane

The order of increasing osmotic pressure is

  1. 0.7% KCl
  2. 1.5% KCl
  3. 1.8% KCl
  4. 5.0% KCl
  5. 8.6% KCl

Explanation:

Osmotic pressure is the strength of movement of the solvent of a solution through a semipermeable membrane separating solutions of different  concentration thereby causing the solvent (such as water) to move from a region of high solute concentration to a region of lower solute concentration.

The amount of osmotic pressure through a semipermeable membrane separating solutions of different concentration is given by

π = i×M×R×T

π = osmotic pressure

i = van't Hoff's factor

(M) = molar concentration

(T) = temperature in kelvin

R = ideal gas constant (0.08206 L atm mol⁻¹K⁻¹)

As seen above , the osmotic pressure is directly proportional to the concentration of the solution thus in the order of increasing osmotic pressure we have

  1. 0.7% KCl
  2. 1.5% KCl
  3. 1.8% KCl
  4. 5.0% KCl
  5. 8.6% KCl
