Question

A student is making a salt water solution for a lab experiment. Which of the following would increase in the rate the salt dissolves?(1 point)
Responses

cooling the water
cooling the water

using salt cubes instead of crushed salt
using salt cubes instead of crushed salt

stirring the solution

Answer 1

Stirring the solution.

Reason: Stirring moves fresh solvent to the salt surface and disperses dissolved ions, increasing the dissolution rate. Cooling slows dissolution (lower temperature → slower molecular motion) and salt cubes dissolve slower than crushed salt because they have less surface area.
