Which of the following would not affect the rate of dissolution of salt in a beaker of water?
a. stirring the solution
b. increasing the pressure of the solution
c. decreasing the size of the salt particles
d. increasing the temperature of the solution

Option (b) is the correct answer.

Explanation:

When we stir a solution then its particles start to move from their initial position leading to more number of collisions between them.

As a result, rate of dissolution increases with stirring.

When we increase the pressure then no change in dissolution occurs because in liquids and solids pressure does not play any role is solubility or dissolution.

When we decrease the size of solute particles then there occurs an increase in surface area of solute. Hence, due to this more number of solute particles are able to come in contact with the solvent.

This will lead to more number of collisions. Therefore, rate of dissolution will increase.

Also, when we increase the temperature then molecules of solution will gain kinetic energy leading to more number of collisions which will eventually lead to increase in rate of dissolution.

Thus, we can conclude that out of the given options increasing the pressure of the solution would not affect the rate of dissolution of salt in a beaker of water.

thats a little if u want the answer just look it up on google thats what i do haha : )

a corroding iron, if that's one of your choices
