A solution of 10 grams KCl at 10 degrees Celsius is said to be:

Question

a
unsaturated
b
saturated
c
supersaturated
Question 14
A student is making a salt water solution for a lab experiment. Which of the following would increase in the rate the salt dissolves?

a
cooling the water
b
using salt cubes instead of crushed salt
c
stirring the solution

Answer 1

For your first question regarding the solution of 10 grams of KCl at 10 degrees Celsius, the correct answer is:

a. unsaturated
This is because the solubility of KCl in water at 10 degrees Celsius is higher than 10 grams per 100 mL of water, indicating that the solution can still dissolve more KCl.

For your second question about the factors that would increase the rate at which salt dissolves in water, the correct answer is:

c. stirring the solution
Stirring increases the contact between the solute (salt) and the solvent (water), effectively increasing the rate of dissolution. Other factors that could help (not in your options) would include increasing temperature or using smaller particles of salt, but from the provided options, stirring is the best choice.
