How will the osmotic pressure of an aqueous solution change as evaporation occurs?

When evaporation occurs, the osmotic pressure increases.

Explanation:

Osmotic pressure is defined as the minimum excess pressure that can be applied on the solution to prevent the entry of the solvent into the solution through a semipermeable membrane. The formula to calculate osmotic pressure is given by the equation:

where,

= osmotic pressure

c = concentration of solute

R = gas constant

T = temperature

As, concentration of solute is directly proportional to the osmotic pressure. So, when concentration increases, osmotic pressure also increases and vice-versa.

Evaporation is a process when liquid changes its state to gaseous state by increasing the temperature. In this process, solvent particles escape and more and more solute particles remain in the solution. So, concentration of solute particles increases.

Hence, evaporation causes increase in the osmotic pressure.

imma come back to you hold on

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
