Final answer:
Increasing the solute concentration will raise the osmotic pressure of a solution.
Step-by-step explanation:
Osmotic pressure is influenced by the concentration of solutes in a solution. It is directly proportional to the number of solute atoms or molecules and not dependent on the size of the solute molecules. Electrolytes dissociate into their component ions, adding more solute particles into the solution and increasing the osmotic pressure. Therefore, increasing the solute concentration will raise the osmotic pressure of a solution.
