Question

39. What occurs as a salt dissolves in water?
(1) The number of ions in the solution
decreases, and the freezing point decreases.
(2) The number of ions in the solution
decreases, and the freezing point increases.
(3) The number of ions in the solution increases,
and the freezing point decreases.
(4) The number of ions in the solution increases,
and the freezing point increases.

Answer 1

Answer:

4

Explanation:

Salt is NaCl right? when it is added it dissociates thus releasing ions thereby increasing the amount of ions in the solution.

As you might know when the weather is low leading to snow people salt their surroundings making the snow to melt. The snow will melt if its freezing point has been increased thus a lower temperature will be needed to turn it back to snow.

Answer 2

The number of ions in the solution increases, and the freezing point decreases.

What is the freezing point?

The temperature at which a liquid solidifies specifically.

Whenever a solute is added to a solution/solvent, it leads to depression in the freezing point of that solution/solvent. Depression in freezing point of a solution on addition of a solute is a colligative property. A colligative property is a physical property which depends upon the number of solute added not on the nature of solute that means it does not matter whether we are adding 1000 particles of sugar or salt in water, the depression in freezing point will occur by the same °C. Also, the more a solute is added the more will be the depression in freezing point.

Hence, option C is correct.
